[Solved] URGENT - Unable to cast object of type 'ReportClass.ListaReunioes' to type 'Telerik.Reporting.IReportDocument'.

[Manuel]

Hi there telerik,

I updated OpenAcess ORM dll for new Q1 2012, and after that my reports never work again.

When I try see a report, appears a message in report Viewer of this type:

A report instance of type 'ReportClass.ListaReunioes' cannot be created.
Unable to cast object of type 'ReportClass.ListaReunioes' to type 'Telerik.Reporting.IReportDocument'.

My report dll version is 5.3.11.1116

My Radsilverlight dll controls version is 2011.2.712.1040

My OpenAcessORM version is 2012.1.301.2 (Q1 2012 )

Please let me know if this is a conflit library problem, or if could be something else.

Thanks in advance,

Nelson Silva

Hello Manuel,

The error message you get should not have anything to do with the upgrade of the OpenAccess product. Try setting the report to the viewer in code:

ReportClass.ListaReunioes report1 = new ReportClass.ListaReunioes();
ReportViewer1.Report = report1;

to see if you would be able to get a more user friendly error message, check the InnerException and Output window of Visual Studio for more information.

All the best,
Steve
