I'm trying to use a ICallbackEventHandler in a CustomForm in an OL 2010 Web App (OWA).
When I'm trying this MSDN example the website (standard ASP.NET) works without a problem.
However applying the same example to my CustomForm doesn't result in anything useful. When the CallServer(...) js method is executed something happens and the page reloads. But js function ReceiveServerData(...) is never called.
I'm getting no errors whatsoever.
Can anybody tell me if ICallbackEventHandler can be used with OWA 2010? - If not, are there any workarounds?
