The DataSource components are toolbox items and they are dynamically loaded from the Visual Studio toolbox in the Create New Data Sources dialog. Thus most probably you are are missing all Telerik Reporting toolbox items. Once the toolbox items appear, the datasource components will show up in the Create New Data Sources dialog.

Another option is to try our Standalone Report Designer that don't depend on the Visual Studio toolbox.
