In Visual Basic, you set this property in the Open event procedure of a report.

To set the GroupOn property to a value other than Each Value, you must first set the GroupHeader or GroupFooter property or both to Yes for the selected field or expression.

The following example sets the SortOrder and grouping properties for the first group level in the Products By Category report to create an alphabetical list of products.

Private Sub Report_Open(Cancel As Integer) 
    ' Set SortOrder property to ascending order. 
    Me.GroupLevel(0).SortOrder = False 
    ' Set GroupOn property. 
    Me.GroupLevel(0).GroupOn = 1 
    ' Set GroupInterval property to 1. 
    Me.GroupLevel(0).GroupInterval = 1 
    ' Set KeepTogether property to With First Detail. 
    Me.GroupLevel(0).KeepTogether = 2 
End Sub
