I've done something like this, but with formating properties.
The class is QuickFormat toolbar in Download section. The main idea is the existence of a timer that scan objects in the form (class) opened in Form (or class) Designer and change format properties to what is selected in toolbar. Also the timer detects selected control(s) formatting properties and update toolbar objects to reflect object(s) settings as FontName, FontSize,etc (like in Word,Excel).

But the idea is this, a timer that detects if a form designer is active and do something with an object inside it.
