HtmlControlDesigner.PreFilterEvents Method

Sets the list of events that are exposed at design-time for the TypeDescriptor object for the component.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

protected override void PreFilterEvents(
	IDictionary events
)

Parameters

events
Type: System.Collections.IDictionary

An IDictionary that contains the names of the events of the component to expose.

The PreFilterEvents method provides a way to add items to or remove items from the dictionary of events that a designer exposes through a TypeDescriptor object.

The keys in the dictionary of events are the names of the events. The objects are of type PropertyDescriptor.

Notes to Inheritors

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