Used by the designer to remove properties from or add additional properties to the display in the Properties grid or to shadow properties of the associated control.
Namespace: System.Web.UI.Design.WebControls Assembly: System.Design (in system.design.dll)
Control designers use methods that are derived from the ComponentDesigner.PreFilterProperties method to shadow various control properties with corresponding design-time properties that the designer implements, and to add properties to or remove properties from the Properties grid.
Notes to Inheritors:
Override the PreFilterProperties method to add properties to or change attributes of properties in the design-time property collection. Be sure to call the base method before performing other processing.
