In a Page report or an RDL report, you can connect to a data source at design time through the Report Explorer. Use the following instructions to connect to various data providers supported in ActiveReports.

These steps assume that you have already added a Page Report/RDL Report in a Visual Studio project. See Adding an ActiveReport to a Project for further information.
