DataGridComboBox Not updated

Oct 13, 2009 at 6:35 AM

 The following Xaml code is taken from the tutorial example "CheckbookManager"

<dg:DataGridComboBoxColumn Header="Memo" Width="*"  ItemsSource="{Binding Source={x:Static Data:CheckBook.Descriptions}, Mode=OneWay}"  TextBinding="{Binding Memo}">

If I update the combo box by editing, the field does not get updated when I tab away. However the record pertaining to the row is updated. Descriptions is a list of strings generated from list of objects containg the field/Property Memo.

Is this a bug or am I missing something?
