ControlName_BorderDragged ( bordersChanged, newX, newY, newWidth, newHeight, finalResize)
Occurs when you drag a draggable border of a control. This event provides the location and size to which you must set the control in order for its draggable borders to track the mouse cursor. However, you may choose to modify the location or size to which you set the control. For example, you can limit the width of the control so the control's left edge cannot be dragged off of the visible portion of the window.
In addition to changing the size and position of the control, you can also update the sizes and positions of the other controls on the window to account for the change.
