Hi,

I'm looking for adding a parameterized query into my report. I'm currently in a Silverlight 3 project and cannot play with my Viewer.report property like in the videos because the silverlight report viewer has a string report property instead of a report type property.

My question is quite simple :
My application needs to set a parameter to my report generation to filter some stuff. How can I pass a value to the reporting service to make my report generating with the user selection parameter ?

I know that report processing is in server side but if we can't pass some parameters from a silverlight app to the reporting service I really don't know what we would be able to do with Telerik Reporting.

I've also tried to see if IReportingService would be a solution to my problem but unfortunately I didn't found any example about how to use it.

Thanks

Regards,
Steeve

Hello COLIN Thierry,

As my colleague had explained in the following blog post to specify a parameter value you have to use the RenderBegin event of the ReportViewer control . The parameter values can be set through the ParameterValues property of the RenderBegin event argument.

Best wishes,

Hi,

Thanks for your answer, it's the good solution.
In addition to this, I would like to explain that we have to set parameters into the report too, because specifying parameters only in the event will not work. I had to specify them in the parameters of my report at design time.

Regards,

Steeve
