后台:

 1 private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
 2         {
 3         
 4             if(e.Item.ItemType!=ListItemType.Header&&e.Item.ItemIndex>=0)

 9                 }
10                 else
11                 {
12                     ((CheckBox)e.Item.Cells[0].FindControl("record")).Visible=false;
13                 }
14                 try
15                 {
16                     HyperLink link1=((HyperLink)e.Item.FindControl("HyperLink1"));
17                     link1.NavigateUrl="add.aspx?bh="+DataGrid1.DataKeys[e.Item.ItemIndex].ToString();
18                 }
