title: Using multiple datasets in RDLC
body: <p>I am working on rdlc reports, and the reports work just fine. I got stuck when I added one more dataset to the rdlc file. On adding the dataset, it added a data source as well. I ran the project, and the report was no more working giving the error: <strong><em>A data source instance has not been supplied for the data source</em></strong><br /><br />
  Can some one please guide me on what steps to take in order to use multiple datasets. I am using Visual Studio 2012.</p>
