ITypeDescriptorFilterService.FilterAttributes Method (IComponent, IDictionary)

 

Filters the attributes that a component exposes through a TypeDescriptor.

Namespace:   System.ComponentModel.Design
Assembly:  System (in System.dll)

bool FilterAttributes(
	IComponent component,
	IDictionary attributes
)

Parameters

component
Type: System.ComponentModel.IComponent

The component to filter the attributes of.

attributes
Type: System.Collections.IDictionary

A dictionary of attributes that can be modified.

Return Value

Type: System.Boolean

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

This method is called when a user requests a set of attributes for a component. The attributes are added to the dictionary with the attribute's TypeId as the keys and the actual attribute as the value. Implementers of this service can add, remove, or alter existing attribute entries in the dictionary.

Notes to Implementers:

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