Using subreport binding to set ReportSource

[Tracy]

I am using Telerik Report Designer, and I have a report that has many nested subreports. The report works fine, but I am trying to change one subreport based on user input.  I attempted to do this by adding a Binding to ReportSource like this:

 

= IIf(Parameters.Images.Value,"ShowImages.trdx", "NoImage.trdx")

When I run this I get the error

 

I've tried different variations of the Expression, including the full path of the trdx file,  but get the same error. Is there a way to change which file is referenced?

 

Thanks,

Tracy

Hello Tracy,

The SubReport.ReportSource Property expects a value of type ReportSource, not a string.
You have the following options to set the report based on the report parameter value:

1. Use the SubReport.ReportSource expression without any bindings: screenshot.
   
   
2. Bind the value of the ReportSource.Uri property to your expression.
   
   
3. Create a User Function which returns a valid report source and bind the result to the ReportSource property.

Thanks, I'm not sure how I missed I could use an Expression in the report source but this now works exactly as I need it to.
