Hi
I have a topic that I don't understand why it happens.
Sometimes when using the Callback Panel I receive an error that suggests that I should:
__________________________________________________
EO.WEB Controls Client Side Debug Message:
EO.Web control 'Ctl00CallbackPanel1' error message: The callback on 'ctl00_CallbackPanel1'
has failed due to a server side exception. Click OK to see the exception message. (set ClientSideOnError to handle this error).
You can turn off this message by settin Eo.Web.Runtime.DebugLevel to 0 (Not recommended for
debug build).
__________________________________________________
But preferably I would like to understand why I have this error sometimes. For instance when using it in a master page or when having a treeview object as an item in the callback panel trigger...
Best,
ITMA

Hi,
Most of the time this is an exception somewhere in your code and has nothing to do with the CallbackPanel. CallbackPanel merely is reporting the problem to you. If you use IE, you can click "OK" and see if it shows you the detailed error message, you can then trace back to the real problem from there.
Thanks!
