Remarks
This property is only used when NeedleType is set to CustomGeometry.
ImageSource
The source of a custom image.
public ImageSource? ImageSource { get; set; }Property Value
Remarks
This property is only used when NeedleType is set to CustomImage.
NeedleType
The type of needle rendered.
public PointerNeedleType NeedleType { get; set; }Property Value
- PointerNeedleType:
The default value is Rectangle.
Methods
OnRender(DrawingContext)
When overridden in a derived class, participates in rendering operations that are directed by the layout system. The rendering instructions for this element are not used directly when this method is invoked, and are instead preserved for later asynchronous use by layout and drawing.
protected override void OnRender(DrawingContext drawingContext)| Parameter | Type | Description |
|---|---|---|
| drawingContext | DrawingContext | The drawing instructions for a specific element. This context is provided to the layout system. |
