ScrollableControlDesigner Class

Base designer class for extending the design mode behavior of a Control which should receive scroll messages.

Namespace:  System.Windows.Forms.Design
Assembly:  System.Design (in System.Design.dll)

public class ScrollableControlDesigner : ParentControlDesigner

ScrollableControlDesigner provides a base class for designers of controls that respond to scroll messages. In addition to the methods and functionality inherited from the ParentControlDesigner, ControlDesigner, and ComponentDesigner classes, ScrollableControlDesigner provides a WndProc method override that passes WM_HSCROLL and WM_VSCROLL messages to the control at design time.


If a form has its AutoScroll property set to active, the scroll bars are always active in the design-time environment.

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
