Base designer class for extending the design mode behavior of a System.Windows.Forms.Control which should receive scroll messages.
See Also: ScrollableControlDesigner Members
System.Windows.Forms.Design.ScrollableControlDesigner provides a base class for designers of controls that respond to scroll messages. In addition to the methods and functionality inherited from the System.Windows.Forms.Design.ParentControlDesigner, System.Windows.Forms.Design.ControlDesigner, and System.ComponentModel.Design.ComponentDesigner classes, System.Windows.Forms.Design.ScrollableControlDesigner provides a System.Windows.Forms.Control.WndProc(System.Windows.Forms.Message@) method override that passes WM_HSCROLL and WM_VSCROLL messages to the control at design time.
If a form has its System.Windows.Forms.Form.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 System.ComponentModel.DesignerAttribute. For an overview of customizing design time behavior, see Extending Design-Time Support.
