Gridview用法大全。

Gridview控件72技。

http://www.cnblogs.com/shiningrise/archive/2007/06/20/791130.html

其中的Gridview 分页功能，word导出，excel导出（图片不能导出），多项选择删除，gridview的编辑，修改，删除功能在最近的项目中使用，感觉挺好。另外那个excel导入功能上面的是不用fileupload控件的，偶稍微修改了一下。

前台页面代码如下：

 

Import.aspx

 1  < asp:GridView ID = " GridView1 "  BorderColor = " Black "   runat = " server "  AutoGenerateColumns = " False "   Font - Size = " 12px "  Width = " 530px "  AllowSorting = " True " >
 2           
 3             < HeaderStyle BackColor = " Azure "  Font - Size = " 12px "  HorizontalAlign = " Center "   />
 4               < RowStyle HorizontalAlign = " Center "   />
 5               < PagerStyle HorizontalAlign = " Center "   />
 6           </ asp:GridView >
 7 
 8     < asp:FileUpload ID = " FileUpload1 "  runat = " server "   />
 9           < br  />
10           < asp:Label ID = " Label1 "  runat = " server "  Text = "" ></ asp:Label >
11           < asp:Button ID = " Button2 "  runat = " server "  Text = " 批量导入 "  onclick = " Button2_Click "   />

后台页面代码如下：

 

 

Import.aspx.cs代码

 1  ///   <summary>
 2       ///  导出到excel文档
 3       ///   </summary>
 4       ///   <param name="sender"></param>
 5       ///   <param name="e"></param>
 6       protected   void  Button2_Click( object  sender, EventArgs e)
