How to use a stored procedure with parameters as a report data source in a WinForms application

The simplest method to use a stored procedure with parameters as a report data source is to create a corresponding TableAdapter in the VS DataSet designer.

To avoid the "Expected parameter was not supplied" error, when using parameterized stored procedure, please make certain whether the corresponding TableAdapter is detached from the XtraReport.DataAdapter property and the necessary parameter value is manually provided. You can use the Report Parameters for this purpose. Finally, fill the report's data source in the XtraReport.BeforePrint event handler by the TableAdapter.Fill() method call.
