Properties

	Name	Description
	Active	Gets or sets a value indicating if the rubberband is active in the parent Viewport control.
	ActiveButtons	Gets or sets a value indicating which mouse buttons are used to draw the rubberband.
	AspectRatio	Gets or sets the aspect ratio which the rubberband will be constrained to.
	BackgroundColor	Gets or sets the background color of a dashed line.
	Bounds	Gets or sets the rectangular area occupied by the rubberband in image pixel coordinates.
	CanRaiseEvents	Gets a value indicating whether the component can raise an event. (Inherited from Component.)
	ClickLock	Gets or sets a value indicating if clicking on the Viewport without moving the mouse starts or finishes a rubberband.
	ConstrainPosition	Gets or sets a value indicating if the RubberBand can be drawn outside the image area.
	Container	Gets the IContainer that contains the Component. (Inherited from Component.)
	Cursor	Gets or sets the cursor which is displayed in the parent Viewport when active.
	CursorPad	Gets or sets the amount of padding for the cursor to change and to allow adjusting the existing selection.
	DesignMode	Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)
	EndPoint	Gets or sets the end point of the Rubberband. Normally this is the bottom-right corner.
	Events	Gets the list of event handlers that are attached to this Component. (Inherited from Component.)
	Inverted	Gets or sets a value indicating if the rubberband is drawn inverted.
	IsDragging	Gets or sets a value indicating whether the Rubberband is being dragged.
	MoveCursor	Gets or sets the cursor used when moving the rubberband.
	MoveWhenInside	Gets or sets a value indicating if the rubberband can be moved with the mouse.
	Parent	Gets or sets the parent ViewPort control.
	Pen	Gets or sets a value of the pen which is used to draw the rubberband.
	Persist	Gets or sets a value indicating if the rubberband continues to display after the mouse button is released.
	Site	Gets or sets the ISite of the Component. (Inherited from Component.)
	SnapToPixelGrid	Gets or sets a value indicating if the rubberband snaps to a grid occupied by one image pixel.
	StartPoint	Gets or sets the starting point of the Rubberband. Normally this is the top-left corner.
	Visible	Gets or sets a value indicating if the rubberband is currently visible.

Remarks

Allows entities to be drawn onto a Viewport by clicking and dragging with the mouse. Derived classes can draw lines, rectangles, and ellipses and be used to draw primitives and make region selections.
