Hi,
I have started using the Telerik Reports and am a bit stumped. In case it matters, I am using the 3.2.9.1211 version of the Silverlight Report Viewer and the 4.0.10.423 version of the engine on the server.
I made a report that didn't use any parameters which successfully loaded in the Silverlight Report Viewer. I then modified the report to accept report parameters for a start time and end time. They are bound to the equivalent parameters in a sql query.
When I run the version with parameters the report viewer finishes with the following message:
Error: Value cannot be null.
Parameter name: typeName
I have checked in the ItemBinding event and the sender appears to have the correct data from the silverlight client. I have tried using string and DateTime data types, in the parameter definition and also sent by the silverlight client.
Though one oddity. I noticed in the report definition defines its type at ReportParameterType.DateTime whereas silverlight sends a System.DateTime. Would that be a cause for problems?
Cheers,
Clint

Hi Clint Singer,

Each version's viewer is build against the respective report engine's version, so our recommendation would be to use the same versions of the engine and the viewer.
