Using custom TypeEditor does not notify parent property

[Rob Mayo]

I have built a custom UITypeEditor for picking web colors for my server control. It's pretty much the same typeeditor as the one you get when you select bgcolor of a document in an aspx page. Since I couldn't figure out which one it was, I decided to build one myself.

It seems to work fine, but the properties I've set to use the editor have the NotifyParentProperty attribute set to True. If I type in the property grid, it notifies the parent property and redraws the control on the page. If I use the editor, it doesn't notify. It waits for me to update some other property before redrawing.

Is there some code I need to implement to get it to notify that I've changed a property?
