A custom event in a user control is not handled by the page

[evgeniosc]

A user control (e.g ctl) is contained in page1.aspx.

On click of a button, contained in the user control, the user control raise a custom event (evt).

The page that contains the user control has a function that handles the raised event but the event handler in page1 is never called.

I used Visual Studio debugger and after executing the raiseevent statement the event handler is never called.
