[2005] Page Control Events

[SLH]

I have a class that inherits from Page.
In the OnLoad method i'm looping through all controls on the page (recursively) before i call base.OnLoad. If the control is a ImageButton (in this example) then i want to add an event handler for its clicked event.

if (Ctrl is ImageButton)
{
    ((ImageButton)Ctrl).Click += new ImageClickEventHandler(ImageButtonClick);
}

This code definatly gets called for each control that is an ImageButton.

My ImageButtonClick event is as below:

public void ImageButtonClick(object sender, ImageClickEventArgs e)
{
    new GUIWebEvent(sender.ToString(), "Click").Raise();
}

This NEVER gets called. I've double checked this by inserting int x = 0;x = 1 / x; within the method, so i know it never gets called.

Any ideas why? My only thought is that i'm doing it in the OnLoad method, but i'm pretty stuck as to how i can get this to work.
