删除代码背后的asp.net事件

Question

I want to remove an event in code behind.

For example my control is like this.

<asp:Textbox ID="txtName" runat="server" OnTextChanged="txtName_Changed" AutoPostBack="true" />

I want to remove the OnTextChanged programmatically.. how can I achieve this?

Answer 1

In C#, you can add and remove event handlers quite easily from the code-behind:

// Add event handler:
txtName.OnTextChanged += new EventHandler(txtName_Changed);

// Remove event handler:
txtName.OnTextChanged -= new EventHandler(txtName_Changed);

Answer 2

In VB.NET code:

RemoveHandler txtName.OnTextChanged, addressof txtName_Changed

Or in C#:

obj.Click += new EventHandler(BeAlert); // register an event handler
obj.Click -= new EventHandler(BeAlert); // unregister the same event handler
