以编程方式添加和删除GridView中的事件

我有一个如下的GridView:

    No results found




Protected Sub Results_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
            'do a bunch of work here
End Sub

根据用户输入,有时我想要触发OnRowDataBound事件,有时我不想.

有没有办法以编程方式打开或关闭事件？

以下是以编程方式在VB.NET中添加和删除事件的示例代码:

If CheckBox1.Checked Then
    AddHandler Results.RowDataBound, AddressOf Results_RowDataBound
Else
    RemoveHandler Results.RowDataBound, AddressOf Results_RowDataBound
End If
