ContentDesigner.PreFilterEvents(IDictionary) Method

Definition

When overridden in a derived class, allows a designer to add items to the set of events that it exposes through a TypeDescriptor object.

C#
protected override void PreFilterEvents (System.Collections.IDictionary events);

Parameters

events
IDictionary

The EventDescriptor objects that represent the events of the class of the component. The keys in the dictionary of events are event names.

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 EventDescriptor.

In this overridden method, the designer clears all events for this control.

Notes to Inheritors

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