Hi Steve:

>Now lets say my form is up, my button is enabled on the toolbar. How do i disable the button on the toolbar from the form? (interactively)

The only way you can disable it from the form is to "create" the circumstances that the form.IsEnabled() method will interpret to provide the disabled state for the button (or more specifically, its corresponding action).

Once you feel that you have done this, simply issue a cmStateManager.refreshAll('Form Carry') - this will refresh just the 'Form Carry' action and any objects registered to it for a Refresh message.
