User Control Question: Button Onclick Event won't work (won't fire)
Hi all,
I create a webusercontrol and load it to home page dynamicly using Place Holder . However, the Button Onclick Event won't work (won't fire) in my Web user Control.
Here are the codes.
Partial
Class test2 Inherits System.Web.UI.UserControl Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click End SubEnd Class
************************************
I set break point to (Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click). Can anyone tell me whats going wrong with my code? Thanks a lot!

First -- is the web control actually showing up in your page? (I gotta assume it is, since you see a button on it to click).
Second -- did you code any method for the btn_Click event?
Third -- what is the ID of the button? Maybe the Handles statement contains a different ID?
Fourth -- When you set the breakpoint on the method signature line, does the program actually break when you click the button?

For example, writing:List<int> l=new with a space in the end, generally gives me a list of items, and List<int> is selected by default so I can press tab and get it written.
