ComponentDesigner.PreFilterEvents(IDictionary) Method

Definition

Namespace:

System.ComponentModel.Design

Assembly:

System.Windows.Forms.Design.dll

Allows a designer to add to the set of events that it exposes through a TypeDescriptor.

protected:
 virtual void PreFilterEvents(System::Collections::IDictionary ^ events);

protected virtual void PreFilterEvents (System.Collections.IDictionary events);

abstract member PreFilterEvents : System.Collections.IDictionary -> unit
override this.PreFilterEvents : System.Collections.IDictionary -> unit

Protected Overridable Sub PreFilterEvents (events As IDictionary)

Parameters

events

IDictionary

The events for the class of the component.

Remarks

This method provides a way to add items to the dictionary of events that a designer exposes through a TypeDescriptor.

The keys in the dictionary of events are the names of the events. The objects are of type PropertyDescriptor. This method is called immediately before the PostFilterEvents method.

Notes to Inheritors

You can directly modify the dictionary that is accessible through the events parameter, or you can leave it unchanged. If you override this method, call the base implementation before you perform your own filtering.
