Could not determine a MetaTable. A MetaTable could not be determined for the data source 'SqlDataSource1' and one could not be inferred from the request URL. Make sure that the table is mapped to the data source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute.


I add one Sqldatasource (configured with database table)

and Gridview(DATA Source: Sqldatasource1)

then above comes on debugging.
