Compatible ASP.NET AJAX version for Reporting 5.0.11.316

[Quan Nguyen]

Hi,
I have this error "Unable to cast object of type 'RTLReportViewer.reportTemplates' to type 'Telerik.Reporting.IReportDocument'." when trying to open a Telerik.Reporting report on a webpage. The report is designed/created withTelerik.Reporting 5.0.11.316 version and the aspx page is using Register Assembly="Telerik.ReportViewer.WebForms, Version=4.1.10.921. I have no problem displaying  reports designed inTelerik.Reporting 4.1.10.921 version.


My question is which version of ASP.NET AJAX  i should use to show the report correctly?


Thanks
Quan

Hey Quan,

No, the Web-ReportViewer is also a part of the Report-Assembly, not of the ASP.NET AJAX.

So the solution should be, to use this line:
Register Assembly="Telerik.ReportViewer.WebForms, Version=5.0.11.316
