Methods
ArrangeOverride(SizeF)
Arranges the RadTaskDialogControlElement to its final location. The element must call the Arrange method of each of its children.
Declaration
protected override SizeF ArrangeOverride(SizeF finalSize)Parameters
finalSize
The size that is available for element.
Returns
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
Remarks
In this method call to the Arrange method of each child must be made.
CreateChildElements()
Called by the element when constructed. Allows inheritors to build the element tree.
Declaration
protected override void CreateChildElements()Overrides
CreateHorizontalScrollBarElement()
