Hi MikeB,
Thank you for the feedback. The value is selected and it is not shown in the DTP field because when you set the MinDate property it is automatically synchronized with the NullDate property. Hance when you set the MinDate as value, you actually set the NullDate property. When the current value is equal to the NullDate value then the display field is empty by design. Please write me back again if you need more information.
All the best,
