ArrangeOverride(SizeF)

Arranges the RadElement to its final location. The element must call the Arrange method of each of its children.

Declaration

protected override SizeF ArrangeOverride(SizeF finalSize)

Parameters

System.Drawing.SizeF finalSize The size that is available for element.

Returns

System.Drawing.SizeF The rectangle occupied by the element. Usually `finalSize`. Should you return different size, the Layout system will restart measuring and rearranging the items. That could lead to infinite recursion.

Overrides

LightVisualElement.ArrangeOverride(SizeF)

Remarks

In this method call to the Arrange method of each child must be made.

Returns

System.Drawing.SizeF The minimum size required by the element to be completely visible. Cannot be infinity.

Overrides

LightVisualElement.MeasureOverride(SizeF)

Remarks

In this method call to the Measure method of each child must be made.
