How do I get the number of rows returned from an objectdatasource?

End sub

try like this

Protected Sub ObjectDataSource_Selected(ByVal sender As Object, ByVal e As ObjectDataSourceStatusEventArgs)
    
    Dim dt As DataTable = DirectCast(e.ReturnValue, DataTable)
    
        
    Dim count As Integer = dt.Rows.Count
End Sub

 That worked great. Thanks

Do you have any idea why intAffectedRows = e.AffectedRows does not work even though its a valid syntax?

It will return number of Rows affected when you are inserting or Updating records
