Hello,
I am running a report I built and I get:
An error has occurred while processing Report '':
Specific cast is not valid.
How am I supposed to debug this? I have no idea what is causing this.

Hello Brian,
You can debug your code only if you have referenced and using your reports in an actual application (be it windows forms or web forms).

Hello,
Even if I run in a web form, the error is with one of the expressions probably, but I can't figure out which one when I don't even get a stack trace; is there some way to figure this out? Can you enable logging to event log or something?
Thanks.

Check the output window in Visual Studio. Also the error is most likely coming from your code behind (i.e. if you have user functions etc.) so place a debugger there to step through your code.
Note that the expression language is not a programming language and you should rely on the syntax described in Telerik's documentation: http://www.telerik.com/help/reporting/designing-reports-item-binding-expressions.html

Hey,
That's the thing; I had verified it and it was clearly within the report; I just fixed the issue and that was because of something within the expression. So that's my concern, is how to figure that out... Cause for a second there, I thought I was using a Microsoft product :-) Just kidding.
Thanks.
