Methods
ArrangeContent()
Handles custom arrange logic when overridden in any UIElement instance.
protected override void ArrangeContent()Remarks
This method is called during the arrange pass to position and size the element's content within its final bounds. The element's position and size are already determined by the layout system and available in the ActualBounds property.
When implementing this method:
- Position child elements within the available space;
- Respect the element's padding when positioning content;
- Handle any content-specific layout requirements;
- Call Arrange() on child elements if needed.
MeasureContent()
Handles custom measure logic when overridden in any UIElement instance.
protected override Size MeasureContent()Returns
Remarks
This method is called during the measure pass to determine the desired size of the element. The returned size should represent the natural size of the element's content, without considering any constraints, margins, or padding.
When implementing this method:
- Return the natural size needed to display the content;
- Do not include padding, margins, or borders in the returned size;
- Consider the content's actual dimensions (e.g., text length, image size);
- Return Empty if the element has no content.
OnRender(IRenderContext)
Handles custom render logic when overridden in any UIElement instance.
protected override void OnRender(IRenderContext context)Parameters
contextIRenderContextThe context to render with.
