I assume you are using a dynamic control--
Be SURE the control exists when you post back to your page.
if the control doesn't exist when the page posts back, it
cannot receive the vent.
so, load the control regardless of the value
of "IsPostBack".
2ndly, do you add a handler when the control is first
rendered? you need to assign some routine to handle the
event:
AddHandler myControl.MyEvent Addressof MyEventHandler
unless you are using member-level "WithEvents" variable
for your control.
