我有一个如下所示的GridView:
<asp:GridView ID="Results" runat="server" OnRowDataBound="Results_RowDataBound">
<EmptyDataTemplate>No results found</EmptyDataTemplate>
</asp:GridView>
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,有时我不会。
有没有办法以编程方式打开或关闭事件?

以编程方式add and remove events in VB.NET的示例代码:
If CheckBox1.Checked Then
AddHandler Results.RowDataBound, AddressOf Results_RowDataBound
Else
RemoveHandler Results.RowDataBound, AddressOf Results_RowDataBound
End If

在您的事件处理程序中添加if并在不需要时忽略该事件会不会更容易?
