How to: Enable Indicator Value's Changing via a Mouse Click
This example demonstrates how to enable the capability for end-users to change a needle's value via a mouse click. To do this, set the ValueIndicatorBase.IsInteractive property to True as shown below.
Note that although in this example, only the ArcScaleNeedle class is used, the IsInteractive property is available in all ValueIndicatorBase class descendants, and therefore it is available in all value indicators.
