I'm getting the error "Unable to find connection string for data source " when clicking the submit button on the Report Viewer - even though I have set up my data source and when clicking 'Execute Query' from within the SQL Builder of the Data Source Configuration Wizard - I do get data displayed on the screen.
What could cause this error?
Yes. That took care of it. Thanks!
Hi,
Ok, I think that the problem is that you need to manually copy the connection strings stored in the app.config file of your class library to the Web.config. I reviewed the Walkthrough and that step is missing.
Hope it helps.
Thanks,

I duplicated the steps in the User Guide in the chapter "Creating a Report and Integrating It Into a Silverlight Application". So, I think I have a SL app with the Report and XAML in the same project, using server side rendering. I was going to attach print screens, but don't see how to do that here.
Are you working in WPF or SL? Are you using client side or server side rendering? Are the Report and the XAML that contains the Viewer within the same project?
