Excel VSTO & # 8594; Hide / show ribbon based on another ribbon button

Question

We are creating Excel 2007 AddIn using VSTO. Now we have a script in which there are 2 buttons. Button "A" and button "B". The B'needs button should be hidden based on a click on the A button.

But since the ribbon bar is not updated dynamically, we cannot see the changes in the ribbon panel.

I heard from some blocks, we should use callback methods for the same.

Could you explain and put a piece of code on how to do this?

Would be very grateful if anyone could help as soon as possible ...
