Assembly: System.Web (in System.Web.dll)
Return ValueType: System.Int32
The number of rows inserted; otherwise, -1, if the number is not known.
The default return value is -1, which means that an unknown number of rows were inserted. To return a different value, set the AffectedRows property of the ObjectDataSourceStatusEventArgs object of the Inserted event. The number of affected rows is typically returned by the Insert method for the business object, and that value is available from the ReturnValue property of the ObjectDataSourceStatusEventArgs object of the Inserted event.
