| When I use the following code to navigate from the toolbar, I get an error (recordID) which is the primary key of my table is zero. Everything works fine if the table has records. Michael Private Sub BO_Navigated(ByVal e As MicroFour.StrataFrame.Business.NavigatedEventArgs) Handles BuildTypeBO1.Navigated SetListViewIndex(BuildTypeBO1.RecordID) End Sub |

| | If there are no records, then accessing any strong-typed property will throw an error. The easiest way to avoid this is to test on the count of the business object like this: If BuildTypeBO1.Count > 0 Then
SetListViewIndex(BuildTypeBO1.RecordID)
End If
