Event Data
The IndicatorLeave event's data class is IndicatorLeaveEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Indicator | Gets the object, for which either the RangeBase.IndicatorEnter or RangeBase.IndicatorLeave event has been raised. Inherited from IndicatorEnterLeaveEventArgs. |
| NewValue | Gets the new value of a property. Inherited from ValueChangedEventArgs. |
| OldValue | Gets the old value of a property. Inherited from ValueChangedEventArgs. |
Remarks
The IndicatorLeave event occurs if a value indicator that previously entered the current range (for which the RangeBase.IndicatorEnter event was raised) now gets its ValueIndicatorBase.Value property less than the RangeBase.StartValue or greater than or equal to the RangeBase.EndValue properties of the current range. Note that the IndicatorLeave event is invoked irrespective of the way an indicator’s value was changed - either via mouse-click on a range or programmatically via code.
The RangeBase.IndicatorEnter and IndicatorLeave events can be used together for various purposes (e.g. to create a state indicator).
