A Borders object specifies the frame and draggable borders that surround a control. A frame is a thin rectangle that surrounds a control on all sides. A draggable border is a rectangular strip of configurable thickness you can place on any combination of the edges of a control. When the application handles the BorderDragged event for the control, users can drag the borders to resize or move the control.
When a control fills a rectangular view area of an application window, you can enable the draggable borders to implement splitter bars that resize the view. Although you can implement splitter bars in some environments without using draggable borders, some environments do not provide any other way to create a splitter bar. For other environments, creating a resizable view using draggable borders is sometimes simpler than using a separate splitter bar. You can also disable the BorderDragged event for a control to use borders for their cosmetic effect only.
