I'm developing an Ajax keypad (C# / ASP.Net 3.5 / VS 2008) using the
updatepanel so that a full visible postback doesn't occur with each button
press.

I've decided to try and wrap the functionality into a user control,
providing events for when ok and cancel is pressed so that the caller (in
this case a page with the control on it) can then query for the keypad's
final value. If I remove the UpdatePanel, the events that the caller
subscribes to are fired and handled correctly, but with the Ajax bit
enabled, the events don't appear to fire.

I'm assuming this is because of the something which exists in the void of my
knowledge regarding Ajax, and the server side interactions that relate to
it.

Any help on how to get this working would be appreciated.

Thanks.
Daniel.

You need to setup a trigger in your update panel to so it will update with a
button is pressed in your user control.
