How can I remove unused datasources from Report Builder?

Question

I am using Report Builder 3.0 to create, deploy and manage reports for my .NET application. I create a new datasource with network credentials which are stored in the report server and point to that shared datasource when I build the reports.

My question is:

Why can't I remove old datasource connections from Report Builder 3.0 Data Source Properties wizard dialog? I've already deleted those unused datasource from report server. But report builder is still showing them as available datasource. Are there any solutions for this?

Thanks in advance.

Answer 1

Edit %localappdata%\Microsoft\Report Builder\11.0.0.0\user.config and delete the obsolete values.

Answer 2

Someone proposed a solution for this problem on Microsoft Connect since 2011.

Alternatively, you can clear all recent items from Report Builder Options Dialog (File->Options). But please take note that it will also clear your connections from Recent Sites and Servers.

Hope this will help you.
