从编程的GridView添加和删除事件 [英] programatically adding and removing events from a GridView

问题描述

我有一个GridView象下面这样：

I've got a GridView like below:

<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

基于用户输入的，有时候我想OnRowDataBound事件，火灾，有时候我不知道。

Based upon user input, sometimes I want the OnRowDataBound event to fire, sometimes I don't.

有没有一种方法以编程方式打开事件或关闭？

Is there a way to programatically turn the event on or off?

推荐答案

下面是一个简单的code到的添加和删除在VB.NET 编程事件：

Here is a sample code to add and remove events in VB.NET programatically :

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