        Asp.net中GridView使用详解(转载),gridview使用详解


        l         GridView无代码分页排序

        l         GridView选中,编辑,取消,删除

        l         GridView正反双向排序

        l         GridView和下拉菜单DropDownList结合

        l         GridViewCheckBox结合

        l         鼠标移到GridView某一行时改变该行的背景色方法一

        l         鼠标移到GridView某一行时改变该行的背景色方法二

        l         GridView实现删除时弹出确认对话框

        l         GridView实现自动编号

        l         GridView实现自定义时间货币等字符串格式

        l         GridView实现用“...”代替超长字符串

        l         GridView一般换行与强制换行

        l         GridView显示隐藏某一列

        l         GridView弹出新页面/弹出新窗口

        l         GridView固定表头(不用JavaScript只用CSS,2行代码,很好用)

        l         GridView合并表头多重表头无错完美版(以合并33行举例)

        l         GridView突出显示某一单元格(例如金额低于多少,分数不及格等)

        l         GridView加入自动求和求平均值小计

        l         GridView数据导入Excel/Excel数据读入GridView

        1.GridView简单代码分页排序:

        1.AllowSorting设为True,aspx代码中是AllowSorting="True";

        2.默认1页10条,如果要修改每页条数,修改PageSize即可,在aspx代码中是PageSize="12"。

        3.默认的是单向排序的,右击GridView弹出“属性”,选择AllowSorting为True即可。

        4.添加代码:

            protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)

            {

                GridView1.PageIndex = e.NewPageIndex;

                Bind();

            }

        2.GridView选中,编辑,取消,删除:

        后台代码:

        using System;

            }

        //绑定

            public void bind()

            {

                string sqlstr = "select * from 表";

                sqlcon = new SqlConnection(strCon);

                SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

                DataSet myds = new DataSet();

                GridView1.DataBind();

                sqlcon.Close();

            }

        }

         

        前台主要代码:

                                <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                            <asp:Button ID="Button2" runat="server" Font-Size="9pt" Text="删除" OnClick="Button2_Click" />

        6.鼠标移到GridView某一行时改变该行的背景色方法一:

        做法:

        双击GridView的OnRowDataBound事件;

        在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

            {

            //首先判断是否是数据行

                    if (e.Row.RowType == DataControlRowType.DataRow)

                    {

                        //当鼠标停留时更改背景色

                        e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");

                        //当鼠标移开时还原背景色

                        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

                    }

            }

        前台代码:

        <html xmlns="//www.w3.org/1999/xhtml" >

        <head runat="server">

            <title>实现鼠标划过改变GridView的行背景色清清月儿//blog.csdn.net/21aspnet </title>

        </head>

        <body>

            <form id="form1" runat="server">

            <div>

                <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"

                    DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                    <Columns>

                        <asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />

                        <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />

                        <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址" />

                        <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                    </Columns>

                    <FooterStyle BackColor="White" ForeColor="#000066" />

                    <RowStyle ForeColor="#000066" />

                    <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                    <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                    <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                </asp:GridView>

                <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"

                    SelectCommand="SELECT top 5 [身份证号码], [姓名], [员工性别], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

           

            </div>

            </form>

        </body>

        </html>

         

        7.鼠标移到GridView某一行时改变该行的背景色方法二:

        做法:和上面的一样就是代码不同

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

            {

                //如果是绑定数据行

                if (e.Row.RowType == DataControlRowType.DataRow)

                {

                    //鼠标经过时,行背景色变

                    e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");

                    //鼠标移出时,行背景色变

                    e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

                }

            }

        8.GridView实现删除时弹出确认对话框:

        实现方法:

        双击GridView的OnRowDataBound事件;

        在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

            protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

            {

                //如果是绑定数据行

                if (e.Row.RowType == DataControlRowType.DataRow)

                {

                     if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)

                    {

                        ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除:/"" + e.Row.Cells[1].Text + "/"吗?')");

                    }

                }

            }

        9.GridView实现自动编号:

        实现方法:

        双击GridView的OnRowDataBound事件;

        在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

            protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

            {

                if (e.Row.RowIndex != -1)

                {

                    int id = e.Row.RowIndex + 1;

                    e.Row.Cells[0].Text = id.ToString();

                }

            }

         

        注意这时最好把前台的第一列的表头该为“编号”,因为以前的第一列被“吃掉”了。

        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                                OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                                <FooterStyle BackColor="White" ForeColor="#000066" />

                                <Columns>

                                    <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                    <asp:BoundField DataField="姓名" HeaderText="用户姓名" />

                                    <asp:BoundField DataField="员工性别" HeaderText="性别" />

                                    <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />

                                    <asp:CommandField HeaderText="选择" ShowSelectButton="True" />

                                    <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                    <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />

                                </Columns>

                                <RowStyle ForeColor="#000066" />

                                <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                                <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                            </asp:GridView>

        10.GridView实现自定义时间货币等字符串格式:

        解决方法:

        在asp.NET 2.0中,如果要在绑定列中显示比如日期格式等,如果用下面的方法是显示不了的

        <asp :BoundField DataField="CreationDate"

        DataFormatString="{0:M-dd-yyyy}"

        HeaderText="CreationDate" />

        主要是由于htmlencode属性默认设置为true,已防止XSS攻击,安全起见而用的,所以,可以有以下两种方法解决

        1、

        <asp :GridView ID="GridView1" runat="server">

        <columns>

        <asp :BoundField DataField="CreationDate"

        DataFormatString="{0:M-dd-yyyy}"

        HtmlEncode="false"

        HeaderText="CreationDate" />

        </columns>

        </asp>

        将htmlencode设置为false即可

        另外的解决方法为,使用模版列

        <asp :GridView ID="GridView3" runat="server" >

        <columns>

        <asp :TemplateField HeaderText="CreationDate" >

        <edititemtemplate>

        <asp :Label ID="Label1" runat="server"

        Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>

        </asp>

        </edititemtemplate>

        <itemtemplate>

        <asp :Label ID="Label1" runat="server"

        Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>

        </asp>

        </itemtemplate>

        </asp>

        </columns>

        </asp>

        前台代码:

        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"

                    DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                    <Columns>

                        <asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />

                        <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />

                        <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                        <asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />

                        <asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />

                    </Columns>

                    <FooterStyle BackColor="White" ForeColor="#000066" />

                    <RowStyle ForeColor="#000066" />

                    <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                    <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                    <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                </asp:GridView>

                <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"

                    SelectCommand="SELECT top 5 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

        附录-常用格式化公式:

        {0:C}  货币;

        {0:D4}由0填充的4个字符宽的字段中显示整数;

        {0:000.0}四舍五入小数点保留第几位有效数字;

        {0:N2}小数点保留2位有效数字;{0:N2}%   小数点保留2位有效数字加百分号;

        {0:D}长日期;{0:d}短日期;{0:yy-MM-dd}   例如07-3-25;;{0:yyyy-MM-dd}  例如2007-3-25

        11.GridView实现用“...”代替超长字符串:

        解决方法:数据绑定后过滤每一行即可

        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

                {

                    DataRowView mydrv;

                    string gIntro;

                    if (GridView1.PageIndex == 0)

                    {

                        mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名

                        gIntro = Convert.ToString(mydrv["家庭住址"]);//所要处理的字段

                        GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);

                    }

                    else

                    {

                        mydrv = myds.Tables["飞狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];

                        gIntro = Convert.ToString(mydrv["家庭住址"]);

                        GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);

                    }

                } 

        调用的方法:

            public string SubStr(string sString, int nLeng)

            {

                if (sString.Length <= nLeng)

                {

                    return sString;

                }

                string sNewStr = sString.Substring(0, nLeng);

                sNewStr = sNewStr + "...";

                return sNewStr;

            }

        12.GridView一般换行与强制换行:

        首先设置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" ItemStyle-Width="100" />gridview里有一列绑定的数据很长,显示的时候在一行里面显示,页面拉得很宽。原因是连续英文段为一个整体导致的,在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就可以。如果要给所有的列增加此属性:

         protected void Page_Load(object sender, EventArgs e)

            {

                //正?;恍?/p>

                GridView1.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");

                //下面这行是自动换行

                GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");

                if (!IsPostBack)

                {

                     bind();//调用数据绑定即可

                }

            }

        总之:善用CSS的word-break:break-all;word-wrap:break-word属性即可,这个属性是通用的对于顽固的南换行问题都可以解决,不局限于GridView。

        13.GridView显示隐藏某一列:

        解决方案:

        public void bind()

            {

                string sqlstr = "select top 5 * from 飞狐工作室";

                sqlcon = new SqlConnection(strCon);

                SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

                DataSet myds = new DataSet();

                sqlcon.Open();

                myda.Fill(myds, "飞狐工作室");

                GridView1.DataSource = myds;

                GridView1.DataKeyNames = new string[] { "身份证号码" };

                GridView1.DataBind();

                sqlcon.Close();

                GridView1.Columns[3].Visible = false;//一开始隐藏

                CheckBox1.Checked = false;//如果不这样后面的代码会把他True

            }

        双击CheckBox1,在CheckedChanged方法里写上代码,最后代码如下:

        protected void CheckBox1_CheckedChanged(object sender, EventArgs e)

            {

                 GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;

                 Response.Write("GridView1的第4列现在的显示隐藏状态是:"+GridView1.Columns[3].Visible.ToString());

            }

        注意:CheckBox1的AutoPostBack要True!

        14.GridView弹出新页面:

         <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                                OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"  >

                                <FooterStyle BackColor="White" ForeColor="#000066" />

                                <Columns>

                                    <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                    <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                                    <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                    <asp:HyperLinkField HeaderText="姓名" Text="姓名" DataNavigateUrlFields="姓名" DataNavigateUrlFormatString="Default6.aspx?GoodsID={0}" Target="mainframe" NavigateUrl="~/Default6.aspx" DataTextField="姓名" >

                            </asp:HyperLinkField>

                                    <asp:CommandField HeaderText="选择" ShowSelectButton="True" />

                                    <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                    <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />

                                </Columns>

                                <RowStyle ForeColor="#000066" />

                                <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                                <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                            </asp:GridView>

        DataNavigateUrlFields是链接的字段名,DataNavigateUrlFormatString是路径。

        15.GridView固定表头(不用javascript只用CSS!,很好用)

        代码:

        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "//www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

        <html xmlns="//www.w3.org/1999/xhtml" >

                <style>

        .Freezing

           {

           

           position:relative ;

           table-layout:fixed;

           top:expression(this.offsetParent.scrollTop);  

           z-index: 10;

           }

        .Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}

        </style>

                                OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowCreated="GridView1_RowCreated"  >

                                <FooterStyle BackColor="White" ForeColor="#000066" />

                                <Columns>

                                    <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                    <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                                    <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                    <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>

                            </asp:GridView>

                </div>

            </form>

        </body>

        </html>

        用法:CSS设如上的样式,HeaderStyle加CssClass="Freezing,套住GridView的Div设置高度宽度 <div>16.GridView合并表头多重表头无错完美版(以合并33行举例)

        后台代码:

            protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)

            {

                switch (e.Row.RowType)

                        tcHeader.Add(new TableHeaderCell());

                        tcHeader[7].Attributes.Add("bgcolor", "Khaki");

                        tcHeader[7].Text = "姓名";

                        tcHeader.Add(new TableHeaderCell());

                        tcHeader[8].Attributes.Add("bgcolor", "Khaki");

                        tcHeader[8].Text = "出生日期";

        17.GridView突出显示某一单元格(例如金额低于多少,分数不及格等)

        解决方案:主要是绑定后过滤

         GridView1.DataBind();

                for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

                {

                    DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];

                    string score = Convert.ToString(mydrv["起薪"]);

                    if (Convert.ToDouble(score) < 34297.00)//大家这里根据具体情况设置可能ToInt32等等

                    {

                        GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Red;

                    }

                }

                sqlcon.Close();

        前台代码:

                </div>

            </form>

        </body>

        </html>

        18.GridView加入自动求和求平均值小计

        解决方案:    

        private double sum = 0;//取指定列的数据和,你要根据具体情况对待可能你要处理的是int

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

            {

               

                if (e.Row.RowIndex >= 0)

                {

                    sum += Convert.ToDouble(e.Row.Cells[6].Text);

                }

                else if (e.Row.RowType == DataControlRowType.Footer)

                {

                    e.Row.Cells[5].Text = "总薪水为:";

                    e.Row.Cells[6].Text = sum.ToString();

                    e.Row.Cells[3].Text = "平均薪水为:";

                    e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();

                   

                }

            }

        前台:唯一的花头就是设置ShowFooter="True" ,否则默认表头为隐藏的!

        <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" OnRowEditing="GridView1_RowEditing"

                                OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound" ShowFooter="True"  >

                                <FooterStyle BackColor="White" ForeColor="#000066" />

                                <Columns>

                                    <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                    <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                    <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                    <asp:BoundField DataField="出生日期" HeaderText="邮政编码"  />

                                    <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                    <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />

                                    <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                                  

                                </Columns>

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                            </asp:GridView> 

         19.GridView数据导入Excel/Excel数据读入GridView

        解决方案:

        页面增加一个按钮,单击事件添加如下方法:

        protected void Button1_Click(object sender, EventArgs e)

            {

                Export("application/ms-excel", "学生成绩报表.xls");

            }

            private void Export(string FileType, string FileName)

            {

                Response.Charset = "GB2312";

                Response.ContentEncoding = System.Text.Encoding.UTF7;

                Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());

                Response.ContentType = FileType;

                this.EnableViewState = false;

                StringWriter tw = new StringWriter();

                HtmlTextWriter hw = new HtmlTextWriter(tw);

                GridView1.RenderControl(hw);

                Response.Write(tw.ToString());

                Response.End();

            }

        //如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内

            public override void VerifyRenderingInServerForm(Control control)

            {

            }

        还有由于是文件操作所以要引入名称空间IO和Text

        后台代码:

        using System;

        using System.Data;

        using System.Configuration;

        using System.Web;

        using System.Web.Security;

        using System.Web.UI;

        using System.Web.UI.WebControls;

        using System.Web.UI.WebControls.WebParts;

        using System.Web.UI.HtmlControls;

        using System.Data.SqlClient;

        using System.Drawing;

        using System.IO;

        using System.Text;

        public partial class Default7 : System.Web.UI.Page

        {

            SqlConnection sqlcon;

            SqlCommand sqlcom;

            string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";

            protected void Page_Load(object sender, EventArgs e)

            {

                if (!IsPostBack)

                {

                    bind();

                }

            }

           

            public void bind()

            {

                string sqlstr = "select top 5 * from 飞狐工作室";

                sqlcon = new SqlConnection(strCon);

                SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

                DataSet myds = new DataSet();

                sqlcon.Open();

                myda.Fill(myds, "飞狐工作室");

                GridView1.DataSource = myds;

                GridView1.DataKeyNames = new string[] { "身份证号码" };

                GridView1.DataBind();

                sqlcon.Close();

            }

            protected void Button1_Click(object sender, EventArgs e)

            {

                Export("application/ms-excel", "学生成绩报表.xls");

            }

            private void Export(string FileType, string FileName)

            {

                Response.Charset = "GB2312";

                Response.ContentEncoding = System.Text.Encoding.UTF7;

                Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());

                Response.ContentType = FileType;

                this.EnableViewState = false;

                StringWriter tw = new StringWriter();

                HtmlTextWriter hw = new HtmlTextWriter(tw);

                GridView1.RenderControl(hw);

                Response.Write(tw.ToString());

                Response.End();

            }

            public override void VerifyRenderingInServerForm(Control control)

            {

            }

           

        }

        前台:

        <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" 

                                 BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"   >

                                <FooterStyle BackColor="White" ForeColor="#000066" />

                                <Columns>

                                    <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                    <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                    <asp:BoundField DataField="出生日期" HeaderText="邮政编码"  />

                                    <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                    <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />

                                    <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                                  

                                </Columns>

                                <RowStyle ForeColor="#000066" />

                                <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                                <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"  CssClass="ms-formlabel DataGridFixedHeader"/>

                                <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                            </asp:GridView>

                <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="导出" />

        读取Excel数据的代码:这个很简单的

        private DataSet CreateDataSource()

            {

                string strCon;

                strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";

                OleDbConnection olecon = new OleDbConnection(strCon);

                OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);

                DataSet myds = new DataSet();

                myda.Fill(myds);

                return myds;

            }

            protected void Button1_Click(object sender, EventArgs e)

            {

                GridView1.DataSource = CreateDataSource();

                GridView1.DataBind();

            }
