AJAX :: Unhandled Exception During PageMethod After Moving To .NET 4.0?
Jun 29, 2010
I have written an application that relies upon PageMethods. It was working fine in .NET 3.5 where I would rely upon exceptions to signify something failing during the call. I would then alert the user to what ever it was that happened. All was working great. I transitioned to .NET 4.0 as I am intrigued by the Parallel Computing improvements. Now any exception that I throw in the PageMethod in the code behind is met with an Unhandled Exception. Nothing has changed other than the target framework.

My company has an application that handles shopping cart check out processes.The application is written in VB.net with the .NET 2.0 Framework.We are running IIS 6.0 as the web server and have,what we consider,excellent exception handling.For those exceptions that we can't figure out why they're happening,we use Elmah to handle them,package them up,and email them to us.We still see a fair amount of unhandled exceptions,handled by Elmah.
My question is:This is an application that is used by many people on the web at the same time.If there is an unhandled exception (handled by Elmah, mind you),does this then reset the application so that all users who aren't doing anything naughty see the application blow up in front of them when this happens?

I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String
Get
Return txtboxfake.Text
End Get
End Property
Then under page_load of the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtteam.Text = PreviousPage.CurrentCity
txtboxdate.Text = Calendar1.SelectedDate
End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.

This is actually a problem with a local report (RDLC) as opposed to an SQL report but this seemed to be the closest forum. I'm simply trying to have my page programatically open my report in PDF format. Ideally the preview wouldn't have to load at all but the way of doing it in pure code without loading a page with a ReportViewer control seems complicated to me, especially as the report has several subforms, all with different datasources (from an SQL server database).
So I'll settle for a page with a ReportViewer control which automatically opens the report in PDF when the page loads. I can't believe how much code is required for this! There are lots of tutorials on the Internet for this and I've tried several but without success. It seems to always fail at the same line, when adding values to the byte array.

In ASP.NET should we call Session.Abandon() when an unhandled exception occurs?There are many end users that hit "refresh" or "back" in the web browser in order to resubmit the request.I would like to prevent this behavior by resetting the context.TIA.
