An extender provider is a component that provides properties to other components. For example, the ToolTip control is an extender provider. When you add a ToolTip control to a Form, all other controls on the form have a ToolTip property added to their list of properties.
Any component that provides extender properties must implement IExtenderProvider. A visual designer can then call CanExtend to determine which objects in a container should receive the extender properties.
For more information about extender providers, see How to: Implement an Extender Provider.
