SharePoint data source
The SharePoint data source web part retrieves data from a SharePoint server, which can then be provided to a listing web part and displayed. It utilizes web services according to the type of the loaded data (Lists.asmx, Imaging.asmx).
Please note that the SharePoint site URL property of the web part contains a sample URL by default. For the web part to display some data, you need to specify the URL of an existing service/server, and enable the Visible property of the connected Basic repeater web part.
