Commandbars Focus

Hello, when commandbars get focus (by click button, by accelerator keys), active control don't loses focus, then an action is done (ie Save data) before control's validation. Example: an invoice form: user inputs the date in texbox and presses commandbars's Save button: as data isn't validated after textbox's LostFocus or Validate, I can't save the right value. I have a very long project with lots of forms and controls, and i can't put a control before save for every of them (textboxes, grids, checkboxes, etc).
Is there any property for raise a GotFocus before commandbar's Execute event? If not, can you agregate it for next relesase?

Thanks

Sorry for my very bad english

A me.Setfocus o control.setfocus in Execute's events raises the lost focus after Execute procedure is executed, then Saves and then Validates. I need something like and BeforeExecute Event or a commandbars_GotFocus

Thanks
