Methods

ArrangeOverride(Size)

Positions child elements and determines a size for the element.

Declaration
protected override Size ArrangeOverride(Size finalSize)
Parameters
Type Name Description
System.Windows.Size finalSize

The final area within the parent that this element should use to arrange itself and its children.
Returns
Type Description
System.Windows.Size

The actual size used.
Remarks

The startOuterRadius,middleOuterRadius,endOuterRadius, startInnerRadius,middleInnerRadius and endInnerRadius were calculated according to the appropriate ScalePlacement values and then Range's PathFigure was created.

MeasureOverride(Size)

Measures the size in layout required for child elements and determines a size for the element.

Declaration
protected override Size MeasureOverride(Size availableSize)
Parameters
Type Name Description
System.Windows.Size availableSize

The available size that this element can give to child elements.
Returns
Type Description
System.Windows.Size

The size that this element determines it needs during layout.

OnBindIndicatorChanged(DependencyPropertyChangedEventArgs)

Declaration
protected override void OnBindIndicatorChanged(DependencyPropertyChangedEventArgs e)
Parameters
Type Name Description
System.Windows.DependencyPropertyChangedEventArgs e

Property change details, such as old value and new value.
Overrides

OnInitialized(EventArgs)

Raises the System.Windows.FrameworkElement.Initialized event. This method is invoked whenever System.Windows.FrameworkElement.IsInitialized property is set to true internally.

Declaration
protected override void OnInitialized(EventArgs e)
Parameters
