The following example demonstrates how to implement a custom ParentControlDesigner. This code example is part of a larger example provided for the IToolboxUser interface.

Remarks

ParentControlDesigner provides a base class for designers of controls that can contain child controls. In addition to the methods and functionality inherited from the ControlDesigner and ComponentDesigner classes, ParentControlDesigner enables child controls to be added to, removed from, selected within, and arranged within the control whose behavior it extends at design time.

You can associate a designer with a type using a DesignerAttribute. For an overview of customizing design time behavior, see Extending Design-Time Support.
