Brad,
Since you have "control" over the page class instance in this case, you
can override the following method to do what you wish:
protected override void RaisePostBackEvent(IPostBackEventHandler
sourceControl, string eventArgument)
{
base.RaisePostBackEvent (sourceControl, eventArgument);
}
This method is what causes a Button or LinkButton click event to fire.
The Page (base) implementation of this method simply calls
sourceControl.RaisePostBackEvent(eventArgument). You can do whatever
checks you wish here to determine whether to delegate the call to the base
Page class or whether to do nothing and ignore the click event. You can
look in the MSDN docs for a list of controls in the framwork that
implement the IPostBackEventHandler interface.
You can also override the RegisterRequiresRaiseEvent to look for what may
have caused the post back. The method is called after the Loading of
ViewState and before any Load events are called. The only draw back is
that this will only be called for the Button and not the LinkButton.
