ITypeDescriptorFilterService.FilterEvents(IComponent, IDictionary) ITypeDescriptorFilterService.FilterEvents(IComponent, IDictionary) ITypeDescriptorFilterService.FilterEvents(IComponent, IDictionary) ITypeDescriptorFilterService.FilterEvents(IComponent, IDictionary) Method

Definition

Filters the events that a component exposes through a TypeDescriptor.

public:
 bool FilterEvents(System::ComponentModel::IComponent ^ component, System::Collections::IDictionary ^ events);
public bool FilterEvents (System.ComponentModel.IComponent component, System.Collections.IDictionary events);
abstract member FilterEvents : System.ComponentModel.IComponent * System.Collections.IDictionary -> bool
Public Function FilterEvents (component As IComponent, events As IDictionary) As Boolean

Parameters

component
IComponent IComponent IComponent IComponent

The component to filter events for.

events
IDictionary IDictionary IDictionary IDictionary

A dictionary of events that can be modified.

Returns

true if the set of filtered events is to be cached; false if the filter service must query again.

Remarks

This method is called when a user requests a set of events for a component. The events are added to the dictionary with the event names as the keys and the corresponding EventDescriptor objects as the values. Implementers of this service can add, remove, or alter event entries in the dictionary.

Notes to Implementers

Return false only when necessary, because repeated queries to the type descriptor filter service can decrease performance.
