After many years reading this forum... I didn't found the solution to my actual problem... When I tought... this could be a big problem... I have a web app wich doesn't have try catch blocks in every method... so I need to implement a generic solution to handle exceptions and the most important... show some BO exceptions to user inside a MessageUserControl (ASCX) wich uses AJAX. this is the big problem, I tried many solutions, application_error, a specific log module, page_error... and with all I got to the same problem...
The UpdatePanel, when it got an unhandled exception, it fires the events (application_error, page_error) or even the httpmodule, but I think it call an Response.End, wich stops any action in the page... and this is just I don't want to do... I need to display the message to the client. this is the call to show the message...

My page wich gots an unhandled exception are inside an UpdatePanel, if I remove it, the message shows UP! I'm working on this for 5 long days.

I have a web form with about 20 fields all validated, rather than use the validation summary control.
I would like a one line alert at the foot of the form that says something along the lines of "errors were found check the fields highlighted with a *" rather than an explanation for each field that has failed validation.
Seem simple enough in theory but i cant work it out.
Is there a line of VB.net code i could use to determine if validation has failed on one or more of my validators and maybe show a label with the "errors were found please check the fields highlighted with a *" message?
Following is the error log captured:-
The error description is as follows :
Source: mscorlib
Message: Padding is invalid and cannot be removed.
