How can I change the format of the Infragistics UltraDateTimeEditor?

I need 开发者_高级运维by default to set the format like "dd-MMM-yyyy" in UltraDateTimeEditor.

I don't have acces to infragistics controls, but a quick look here shows that there's a method UltraDateTimeEditor.FormatString that sounds like it might be useful. Have you tried setting that to "dd-MMM-yyyy"?
