I was originally under the impression that when I was adding a SF DevEx Form to my application I was actually adding a form that had all of the DevExpress properties on it from the XtraForm.  This is not true, however, since the form does not carry the LookAndFeel property.  This doesn't affect most things, but it does affect the Form Skins effect.  When using a DevEx XtraForm and setting EnableFormSkins the title bar of the forms and the border of the form take on the skin.  I cannot do this with a SF DevEx form.  Is there some way that this property could be added or could we actually inherit from the SF Form and then also from the DevEx form the same way the Inherited UI controls are setup?

This is not an interface (like the controls for a BO), this is a class.  You cannot simply implement an interface and get this functionality.  If you go look at all of the properties on the form and the functionality behind them, it goes to the BaseForm.  If you open up the BaseForm code file in the source code (it is in the Business assembly) you will see that there are 3000 lines of code in this one file alone.  If we were to have an XtraForm with this functionality, we would have to maintain two code bases.  This is not a solution for an interface because if would produce even more code.  If you want this functionality, you will have to take the BaseForm code and create your own XtraForm....but beware because if we make a change to BaseForm you will have a broken application.
