The AutoDisplay property enables the automatic display of features on a McGraphOverlay (the AutoDisplayOverlay). In most cases, optionally setting McGraphOverlay.Template properties for the AutoDisplayOverlay, followed by an assignment to AutoDisplay will be all that is needed for feature display.
Complete control of automatic feature display is accessed through the DisplayOverlays property. And in fact, assigning to this property is just a shortcut to assigning mcgtStandardAutoDisplay or mcgtAnyTemplate to the McDisplayOverlays.AutoDisplayTemplateID property (see Examples).
No PropertyChanged event is fired on assignment; track DisplayOverlays.AutoDisplayTemplateID for changes if you need notifications.
