Hi, I have a report wih multiple datasources and somethimes i have a datasource that is empty. When that happens i get the message: "a data source instance has not been supplied for the data source", but i want show the report because the other sources have data to display. Made me understand? Tks

Ok, i was doing wrong... to fill datasource i was using "merge" : DSData.Table1.Merge(_DSata.table1) but i must have create new: ReportViewer1.LocalReport.DataSources.Add(New Microsoft.Reporting.WinForms.ReportDataSource("Table1", _DSData.table1))
