在HTML页面中就一个按钮.
//////<asp:button id="Button1" style="Z-INDEX: 101; LEFT: 0px; POSITION: absolute; TOP: 8px" runat="server"
Text="导出">
///</asp:button>
和 一个DataGrid
///<asp:datagrid id="DataGrid1" style="Z-INDEX: 102; LEFT: 0px; POSITION: absolute; TOP: 40px" runat="server">
///</asp:datagrid>
aspx.cs 文件的代码是:
////public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.WebControls.DataGrid DataGrid1;
protected System.Web.UI.WebControls.Button Button1;
private void Page_Load(object sender, System.EventArgs e)

DataGrid1.DataBind();
// 在此处放置用户代码以初始化页面
}
