By default, the DisplayColor  property is False. Use the DisplayColor property to let a property display and edit a color expression. For instance, let's say that your object lists a property of long type, but it changes the color for some part of the control. In this case, you can force the property to display the property as a color, and use the color editor to edit the value for the color. The PropertyChange event notifies your application that user is about to change a property. The control fires the PropertyChanged event when the user changes any property in the control. The DisplayCheck, DisplayDate, DisplayFile or DisplaySlider property specifies whether the property displays a checkbox, date, file, or slider.
