	The range selector DrawBackground event only gets called on resizing of parent container. How would one force this event to be triggered without a resize event?

	Hi, The event is triggered when the background is required to render (in a Control.OnRender override). To manually force it to repaint, find the element in the range selector's template and call it's InvalidateVisual method: Code var bckgr = range.Template.FindName("PART_Background", range) as Control; if (bckgr != null) { bckgr.InvalidateVisual(); } You can also try replacing the background control in the template with your own, and include your customization there. Regards, Lyubo
