Dynamic User Controls Raise Events

[Anil.Narla]

Hi,
I created a Base Control Code Behind class which contains a delegate
and event(both declared as public)
and i have all my user controls inheriting from this base control.

Now I have one page which loads one of the above user controls
@runtime.When user clicks on next button on a user control iwant to
raise the event that was declared in my base class which passes id for
the next control and my page will load that user control(it removes
current control and add the next control), But i'm getting compilation
error saying that base class event can be

"The event 'namespacetest.BaseControl.Redirect' can only appear on the
left hand side of += or -= (except when used from within the type
'namespacetest.BaseControl')
"

Please Post the solution.
