Property Value

The value which controls the user interaction with the control's display.

By default, the mouse left button starts and controls the interactive mode. To change this behavior, refer to InteractiveModeMouseButton.

You can change the mouse cursor associated with a particular interative mode with the SetInteractiveModeCursor method.
