ASP.NET 3.5 AJAX and default error handler

[Trapulo]

Hello,
with ASP.NET 2.0 Ajax every unexpected error is managed client-side with a
popup that reports the error to the user. In ASP.NET 3.5 this behavor has
been changed: how can I have a similar behavor? I'd like that every
exception raised from ASP.NET runtime during an asyncpostback is managed in
client side with a popup that reports the error message.

thanks

I belive you have an event you can subscribe to.. So every time error
happens your Javascript function is called.


George.

Hi Trapulo,

As for ASP.NET ajax, you can register the event hander for client-side load
events. One of them is "EndRequest" in which we can detect whether there is
any error during the AJAX request processing. Here is web article mentioned
this:

Hi Trapulo,

In addition to handling errors in Javascript, you can also register an
event handler with the ScriptManager's OnAsyncPostBackError delegate.
For an example for each methods, I suggest you check out

This is interesting, thanks, but I'm not sure about this. The page you
refers says:
"the default behavior is that a browser message box is displayed with an
error message"

this is true in ASP.NET 2, but with ASP.NET 3.5 nothing is displaye when an
error occurs. Why? is this a problem in my application? I think it's by
design..
I'd like to manage errors with custom UI elements as your suggestion or
Steven's one says, but first of all I need to have the standard behavor:
when an exeption is raised, a message box is displayed to the user. Whitout
to write any specific code. How can I have this in ASP.NET 3.5?

thanks

Steven,
the improvement you suggest is interesting. But before to create custom
client side code, I'd like to re-enable the standard behavor I had working
with ASP.NET 2.0: when an error occurs, a message box is displayed with
exception's message. i don't have this starting from ASP.NET 3.5. Is this
possible? Is there some error in my applications, if I haven't this behavor
more?

thanks

Hi Trapulo,

As for the error handling behavior, I will consider consult some other
ASPNET ajax engineers on this. Would you create a very simple ajax project
with a test page demonstrate the behavior so that I can directly refer the
code to other engineers. You can send it to me ("stcheng_At_microsoft.com")

Thanks Trapulo,

I've got it and have forwarded the question to other AJAX engineers to see
whether they have any further ideas on this.

Hi Trapulo,

After discussing with some other AJAX engineer, for the AJAX update panel
error handling behavior ,they also recommend the error handling approach in
the below reference:

# "Handling Errors" section
http://asp.net/AJAX/Documentation/Live/overview/ScriptManagerOverview.aspx

seems the original error behavior is now changed to adopt those error
handling settings(rather than use a fixed default behavior).
