为什么datagrid的删除事件没反应了？？

OK521 2003-06-27 06:30:48

我的datagrid中有一个ondeletecommand事件。名称是：dgrdgroup_del
按钮放在我的模版中。
<asp:button commandname=del runat=server text=删除/>
在后置代码中：
sub dgrdgroup_del(s as object,e as datagridcommandeventargs)
response.write(e.item.cells(0).text)
end sub

第列绑定的是一个label控件。
不管理怎么点也没有反应。急死了，以前总是好的。帮我看看吧。就这么简单。

试试这样吧：
<asp:ButtonColumn Text="删除" CommandName="Delete">
<HeaderStyle Wrap="False" HorizontalAlign="Center"></HeaderStyle>
<ItemStyle Wrap="False" HorizontalAlign="Center"></ItemStyle>
</asp:ButtonColumn>

后台代码：
Private Sub dgrdgroup_DeleteCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrdgroup.DeleteCommand

response.write(e.item.cells(0).text)
end sub

<asp:button commandname=del runat=server text=删除/>
------------------------------>
<asp:button commandname=Delete runat=server text=删除/>
或指定
datagrid1.DeleteCommandName = Del

不要改该CommandName，就用默认的Delete
还有不要使用按钮方式，按了没反应，我是这样的。谁知道为什么。快来告诉我！

怎么不用DataGrid的删除按钮列来实现
如下：
.aspx
<asp:ButtonColumn Text="删除" CommandName="Delete"></asp:ButtonColumn>
.cs
private void DataGrid2_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
response.write(e.item.cells(0).text)
}

private void InitializeComponent()
{
this.studentGrid.SortCommand += new System.Web.UI.WebControls.DataGridSortCommandEventHandler(this.DataGridSorting);
this.studentGrid.DeleteCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.delete);
this.Load += new System.EventHandler(this.Page_Load);

}

private void delete(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{

}

add the following
if(e.CommandName=="del")
