System.Double

Value

Gets or sets the Value that decides the position of the CircularPointer in the CircularScale.

Declaration

public double Value { get; set; }

Property Value

Type	Description
System.Double	double

Remarks

Value property is one of the most important property. Based on the Value property pointer has been positioned on the CircularScale. Value should resides between the start and end value of the scale. If the value of this property is less than StartValue of the CircularScale, then the StartValue of the CircularScale is set to the Value of the pointer. Similarly EndValue of the CircularScale is set to the Value of the pointer when Value is greater that EndValue of the scale.

ValueChangeCompleted

Called when the user is done selecting a new value of the pointer by dragging.

Declaration

public event EventHandler<PointerValueChangedEventArgs> ValueChangeCompleted

Event Type

Type	Description
System.EventHandler<PointerValueChangedEventArgs>

Remarks

This event shouldn't be used to update the pointer value (use PointerPositionChanged event for that), but rather to know when the user has completed selecting a new value by ending a drag.

See Also

EnableDragging

ValueChangeStarted

Called when the user starts selecting a new value of pointer by dragging.

Declaration

public event EventHandler<PointerValueChangedEventArgs> ValueChangeStarted

Event Type

Type	Description
System.EventHandler<PointerValueChangedEventArgs>

Remarks

This event shouldn't be used to update the pointer value (use PointerPositionChanged event for that), but rather to be notified when the user has started selecting a new value by starting a drag. The value passed will be the last value that the pointer had before the change began.

Declaration

public event EventHandler<PointerValueChangingEventArgs> ValueChanging
