I have 2 reports, "report1.rdlc" and "report2.rdlc" and I want to be able to swap betweent the 2 of them in a single report viewer ("rv_1").

I also have 3 buttons:
btn_1 which does:

rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report1.rdlc"
rv_1.RefreshReport()

btn_2 which does:

rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report2.rdlc"
rv_1.RefreshReport()

btn_3 which does:

dim rds as new ReportDataSource
rds.name = 
rds.value = 
rv_1.reset()
rv_1.LocalReport.DataSources.add(rds)
rv_1.RefreshReport()

Now no matter what I put for rds.name and rds.value it leaves me with "A data source instance has not been supplied for the data source 'dataSetName_TableName'.

So my question is; what do I need to put there in order to get this to work correctly?
