By default, the DisplaySlider  property is False. Use the DisplaySlider property to let a property display and edit a long expression between 0 and 100. For instance, let's say that your object lists a property Transparency of long type and so, you can assign a slider control to display and change the transparency for the object. 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, DisplayColor, DisplayFile or DisplayDate property specifies whether the property displays a checkbox, color, file, or date.
