菜鸟求助：关于DataGrid中的“按钮列”，请高手帮帮忙……

[hangsome]

ASP.NET(C#) + Sql Server2000开发Webform

在DataGrid中使用了“按钮列”，对于DeleteCommand，UpdateCommand的事件处理函数，请各位大侠给点示例代码，谢谢！！！

学习，关注……

先看看这吧

[zxl0110]

public void S_topicCommand(Object sender, DataGridCommandEventArgs e) //删除数据
{
if (((LinkButton)e.CommandSource).CommandName == "Delete")
{
conn.Open();
TableCell ItemCell=e.Item.Cells[0];
string ID=ItemCell.Text;
sql="delete from active where ID="+ID+"";
//Response.Write(sql);
//Response.End();
comm=new OleDbCommand(sql,conn);
comm.CommandText=sql;
comm.ExecuteNonQuery();
conn.Close();//删除数据库内记录
Response.Redirect("active_manage.aspx");

}
}

在前台页面用
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 96px; POSITION: absolute; TOP: 48px" runat="server"
AutoGenerateColumns="False" AllowPaging="True" Width="488px" OnPageIndexChanged="DataGrid_PageChanged" OnItemDataBound="MydataGrid_bound" OnItemCommand="S_topicCommand">
调用就行了哈
