This modification occurs through the set of descriptors that a component provides through a <see cref="T:System.ComponentModel.TypeDescriptor" />. The type descriptor will query a component's site for the <see cref="T:System.ComponentModel.Design.ITypeDescriptorFilterService" /> service and, if it exists, the type descriptor will pass all metadata it has collected to this service. The service can then modify the metadata by adding, removing, and altering existing characteristics of the component. </para><para>For example, the properties of a component can be modified through a call to the <see cref="M:System.ComponentModel.Design.ITypeDescriptorFilterService.FilterProperties(System.ComponentModel.IComponent,System.Collections.IDictionary)" /> method. The filter service obtains a dictionary that contains property names and their property descriptors of type <see cref="T:System.ComponentModel.PropertyDescriptor" />. The modifications are implemented using the following logic.</para><list type="table"><listheader><item><term><para>Modification</para></term><description><para>Implementation</para></description></item></listheader><item><term><para>Removal</para></term><description><para>Delete the corresponding entry in the dictionary.</para></description></item><item><term><para>Addition</para></term><description><para>Add the appropriate entry to the dictionary.</para></description></item><item><term><para>Alteration</para></term><description><para>Call existing property descriptor methods, replace the associated property descriptor entry, or replace the entire property key/value pair in the dictionary.</para></description></item></list><para>The return value of <see cref="M:System.ComponentModel.Design.ITypeDescriptorFilterService.FilterProperties(System.ComponentModel.IComponent,System.Collections.IDictionary)" /> determines if this set of properties is fixed.
