I would like to be able to detect when the user collapses the ribbon control. (see the screenshot). I need to resize a Panel control on the form to take advantage of the screen real estate that changes when you collapse and reveal the ribbon toolbar.
The thing is I can't seem to find any events for this control.
I can do this work around the SizeChanged event but it's clunky.
I'm looking for something like:
RibbonControl_CollapseState(sender As Object, e As EventArgs) Handles RibbonControl.CollapseState
