Defines the interface for extending properties to other components in a container.

See Also: IExtenderProvider


public interface IExtenderProvider


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 IExtenderProvider.CanExtend(Object) 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.
