Hi,

I upgraded my Telerik reporting version to the latest version.

I view reports using the Properties dialogue of a ReportViewerall worked fine.

but after some reports, suddenly I get this error:

Invalid report type Exception has been thrown by the target of an invocation.

and I do not can see any reports. (all the reports , others too).

Yesterday I get this error all time. Today the reports worked fine' and suddenly I get this error again.

Can anyone shed any light as to the possible reasons why this might be happening?

Thanks

Chani

I am sorry to hear that you are experiencing issues after the upgrade. We will need more information to investigate the problem. Please install the Fiddler Jam extension then generate a network log and share it with us. Also, please attach a trace listener to your project and send the generated log.
