.NET Framework Class Library

IDesignerFilter..::.PreFilterProperties Method

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

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

Syntax

Visual Basic (Declaration)

Sub PreFilterProperties ( _
    properties As IDictionary _
)

Visual Basic (Usage)

Dim instance As IDesignerFilter
Dim properties As IDictionary

    IDictionary^ properties
)

JScript

function PreFilterProperties(
    properties : IDictionary
)

Parameters

properties: Type: System.Collections..::.IDictionary
The PropertyDescriptor objects that represent the properties of the class of the component. The keys in the dictionary of properties are property names.

Remarks

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

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

Notes to Implementers:

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