Allows a designer to filter the set of member attributes that the component it is designing will expose through the TypeDescriptor object.
[Visual Basic] Overrides Public Sub PreFilterProperties( _ ByVal properties As IDictionary _ ) [C#] public override void PreFilterProperties( IDictionary properties ); [C++] public: override void PreFilterProperties( IDictionary* properties ); [JScript] public override function PreFilterProperties( properties : IDictionary );
This method is called immediately before the corresponding "Post" method.
Notes to Inheritors: If you are overriding this method you should call the base implementation before you perform your own filtering. When overriding this method, it should return the augmented set of attributes. If the method does not modify any attributes, it may just return a reference to its input parameter. If you do make a change to the attributes, you must create a new array.
