In our current MDI Apps the most common UI is having a common Tool bar/strip on the MDI Container/Parent and many MDIChild forms with many Grids in them.

e.g. If the MDIChild 'CustomerForm' is the active form and has three grids GridParent, GridChild1 and GridChild2 on it and if the GridParent is the active control and if the user clicks on the MDIParent's Tool bar/strip to add a new row then the new row is added on the active control (GridParent) but if the users then clicks on GridChild2 and then clicks on the Navigate buttons on the tool bar/strip it should then act on GridChild2 and so on.

In short the tool bar/strip should find out the active form (MDIChild) and then within that form the ActiveControl (GridParent, or GridChild1 or GridChild2) and then act on that Active control.

How would I implement this type of UI in SF as it?
