Hi, I'm combining a Dialog and a CallbackPanel - the Dialog allows users to register for a free trial of my client's products. However, when the user clicks the "Apply" button, the ClientSideBeforeExecute method doesn't seem to be called, i.e. the code branches straight to the server-side cmdApply_Click method. I believe I have followed the example in the Demos_Callback_Features_Client_Event_Handler_Demo code, but I can't get it to work. Code below. Any assistance gratefully received. Mark

Hi,
You have:
ClientSideBeforeExecute="before_execute;"
It should be:
ClientSideBeforeExecute="before_execute"
The property takes a function name.
Thanks!
