The EditorPart.DisplayTitle property returns either the current value of the base Part.Title property or, if the control has no title, a calculated value. The calculated value consists of a localizable resource string for untitled controls. In the cases where no value is assigned to the Part.Title property, the value of the EditorPart.DisplayTitle property differs from the Part.Title property.

Because the EditorPart.DisplayTitle property is designed to be a read-only, calculated property to get the actual current value of the displayed title at run time, do not attempt to use this property to set a title for an System.Web.UI.WebControls.WebParts.EditorPart control. To set a title, use the base Part.Title property.
