To modify the properties of a chat room, use the BeginUpdateChatRoom(ChatRoomInformation, AsyncCallback, Object) method. This method accepts an instance of ChatRoomInformation, which can be constructed using a current instance of the ChatRoom object. The following properties are defined for all chat rooms:

NoteNote

Properties marked with an asterisk (*) are "inherited", and have a default value of null. These properties derive their value from the parent category value. The local value can be explicitly set on any child node to hide the parent value and break the inheritance chain. This option is not available if the parent category sets the ChildrenMustInheritProperties property to true. For more information, see InheritedChatRoomProperty.
