Hello!
Actually I'm testing your Telerik Reporting Product (Telerik_Reporting_2008_3_1402_trial). I have designed a big report (>255 Textboxes ==> I know, that this are many textboxes, but this is real life), so I needed to part the whole report in one main report and in one subreport (don't missunderstand me ==> it is not designed as the master-detail-example yet).
I added a subreport control to the main report and set the reportsource-property to the subreport I created. Then I run my web application in VS 2008 SP1. Everything works fine.
After I close the running web application, Visual Studio tells me, that there are errors and the main report class could/should not be loaded into the designer to prevent data loss.
The two error messages in detail (translated from german VS with google language tools):
1)
german: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

english: Object reference not set to an instance of an object.
2)
german: Die Variable reportZahlung1 wurde nicht deklariert oder nicht zugeordnet.
english: The variable reportZahlung1 has not been declared or not assigned.
So I can't go on with the designing of the report. Interesting is, that when I start the project again, everthing works still fine.
Any suggestions to solve the problem would be very nice.
