title: RDLC - Adding a Data Source in VS2010
body: <p>Greetings.</p>
  
  <p>I have an RDLC file and am wanting to add a data source to it, although without any luck so far.  The data source is a custom class written by myself (just to add, we do this all the time).  We recently converted over to the VS2010 RDLC format which caused some problems, but we've made some changes to our implementation that workaround the more major issues.</p>
  
  <p>So, back to the issue at hand, when I attempt to add my data source to the DummyDataSource list in the RDLC view in VS2010 it just does nothing, however it does add the data source to the list of data sources, but you can't select it from the drop-down list in the RDLC view which means I can't add the data source at all.</p>
  
  <p>Has anyone come across this problem? Is there anything I need to check?  I've searched with fervour and had no luck.</p>
