I have an aspx page that contains an update panel. Within this there are several user controls, each with a label to display an error. Within these controls are more child controls where exceptions are caught and an ExceptionEncountered event is raised to deal with them.
The parent control (with the error label) listens for the ExceptionEncountered event and sets the text of the label accordingly.
The problem is that the label text on the screen does not change.
Any idea what could be wrong?
