How do you do the enabling/disabling of controls, I use an if to check an edit flag on every controls refresh method, of course I use classes for this, this has worked fine, and I like the fact that every control takes care of itself.

>Save: Enabled
>Undo: Enabled
>Delete: Disabled
>Close: Disabled

>But how do you solve the "irrelevent enabled controls" problem? For example, is your Undo and/or Cancel button always enabled? That's my problem; I get downright anal about controls not being enabled that have no function depending on the current form state. In a permanent edit mode, you have to get cute with the interactivechange of your parent classes.
