build fails with ModalPopupExtender when controls have event handlers

[BillE]

I have an asp button and an asp listbox control in a panel which is the
PopupControlID for an Ajax ModalPopupExtender.

It all works great until I create an event handler for the button control,
and then the build fails - before I even put any code into the event
handler.

When the build fails, there is sometimes an error "handles clause requires a
withevents variable defined in the containing type or one of its base
types".

How can I fix this?

Thanks
Bill

Modal or whatever you want with embedded controls just like a normal
ASP.Panel can have...

Let me rephrase my question - how can I fix this ... without buying
something else?
