HI,
I HAVE A DEFAULT WEB FORM WITH A MENU AND A CALLBACKPANEL WITH A MULTIPAGE (and a page) INSIDE WHERE I WANT TO LOAD CONTROLS DYNAMICALLY.
I MADE THIS SIMPLE EXAMPLE TO SIMULATE THE ERROR
THE BUTTON IN THE CONTROL IS A CALLBACKPANEL TRIGGER AND I HAVE THE FOLLOWING ERROR WHEN I CLICK IT.
THANKS.
EO.Web Controls Client Side Debug Message:
EO.Web control 'ctl03_CallbackPanel1' error message (set ClientSideOnError to handle this error):The callback on 'ctl03_CallbackPanel1' has failed because the server did not recognize this callback and processed it as a normal request. This can occur if there are multiple Callback/CallbackPanel controls in the page, and this Callback/CallbackPanel control was initially dynamically loaded but wasn't loaded for this callback.
This can also occur if you have called Response.Redirect on the server side. Callback/CalbackPanel provides a Redirect method for such scenario. Please use the Callback/CallbackPanel's Redirect method in this case.
You can turn off this message by setting EO.Web.Runtime.DebugLevel to 0 (Not recommended for debug build).
