Expandable Props [RESOLVED]

[Aaron Young]

If you're control is inheriting from UserControl or Control it
should have an Invalidate method which triggers a Paint event.

Either way, it doesn't matter, you must have something in your control
that gets called when you want it to draw itself, if so, then that's what you want
to call in the Set of the expandable property in your control.

Those methods that just return True are called by the IDE to see if your
class supports certain things, like supplying a list of the sub-properties and
creating instances of your class.

Edit: Re-reading your post makes me think that maybe you thought the Invalidate call would be in the converter class, it's not,
it's in your UserControl when you expose the property of type GradientStyle. - Aaron.
