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：

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：

</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)  
  
\{   
  
//正常换行  
  
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" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  
  
<html xmlns="http://www.w3.org/1999/xhtml" >  
  
<head runat="server">  
  
<title>GridView固定表头 清清月儿http://blog.csdn.net/21aspnet </title>  
  
<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>  
  
</head>  
  
<body style="font-size=12px">  
  
<form id="form1" runat="server">  
  
<div style="overflow-y: scroll; height: 200px;width:300px" id="dvBody">  
  
<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" 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" />  
  
  
  
</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" 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 style="overflow-y: scroll; height: 200px;width:200px" >  
  
16.GridView合并表头多重表头无错完美版（以合并3列3行举例）  
  
后台代码：  
  
protected void GridView1\_RowCreated(object sender, GridViewRowEventArgs e)  
  
\{   
  
switch (e.Row.RowType)  
  
\{   
  
case DataControlRowType.Header:  
  
//第一行表头  
  
TableCellCollection tcHeader = e.Row.Cells;  
  
tcHeader.Clear();  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[0\].Attributes.Add("rowspan", "3"); //跨Row  
  
tcHeader\[0\].Attributes.Add("bgcolor", "white");  
  
tcHeader\[0\].Text = "";  
  
tcHeader.Add(new TableHeaderCell());  
  
//tcHeader\[1\].Attributes.Add("bgcolor", "Red");  
  
tcHeader\[1\].Attributes.Add("colspan", "6"); //跨Column  
  
tcHeader\[1\].Text = "全部信息</th></tr><tr>";  
  
//第二行表头  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[2\].Attributes.Add("bgcolor", "DarkSeaGreen");  
  
tcHeader\[2\].Text = "身份证号码";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[3\].Attributes.Add("bgcolor", "LightSteelBlue");  
  
tcHeader\[3\].Attributes.Add("colspan", "2");  
  
tcHeader\[3\].Text = "基本信息";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[4\].Attributes.Add("bgcolor", "DarkSeaGreen");  
  
tcHeader\[4\].Text = "福利";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[5\].Attributes.Add("bgcolor", "LightSteelBlue");  
  
tcHeader\[5\].Attributes.Add("colspan", "2");  
  
tcHeader\[5\].Text = "联系方式</th></tr><tr>";  
  
//第三行表头  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[6\].Attributes.Add("bgcolor", "Khaki");  
  
tcHeader\[6\].Text = "身份证号码";  
  
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";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[9\].Attributes.Add("bgcolor", "Khaki");  
  
tcHeader\[9\].Text = "薪水";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[10\].Attributes.Add("bgcolor", "Khaki");  
  
tcHeader\[10\].Text = "家庭住址";  
  
tcHeader.Add(new TableHeaderCell());  
  
tcHeader\[11\].Attributes.Add("bgcolor", "Khaki");  
  
tcHeader\[11\].Text = "邮政编码";  
  
break;  
  
\}

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();

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！

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();  
  
\}
