Name Description

Default size constraints are applied to the layout item and its control. The default size constraints are determined automatically depending upon the type of its control.


This mode is designed to support horizontal alignment of the controls that implement the automatic sizing feature, when they are displayed within a LayoutControl. A layout item’s maximum and minimum sizes are determined automatically. To custom align a control, set its AutoSizeInLayoutControl property to true and specify the control’s alignment via the LayoutControlItem.ContentHorzAlignment property. See Size and Alignment to learn more.


A layout item’s size can be changed within the range which is specified by the LayoutControlItem.MinSize and LayoutControlItem.MaxSize properties.


If the SizeConstraintsType property is set to SizeConstraintsType.Default, the current layout item’s size constraints are automatically determined based upon the type of the layout item’s control.

Custom size constraints can be applied if the SizeConstraintsType property is set to SizeConstraintsType.Custom. To set the constraints in this mode, use the LayoutControlItem.MinSize and LayoutControlItem.MaxSize properties.

When size constraints are applied and OptionsView.UseSkinIndents option is enabled, control sizes might change when changing a paint scheme. This occurs because the real size of a control is affected by layout item padding.

See the Size and Alignment topic for more details.
