Remarks

The BaseLayoutItem class represents the base class for layout items. This class is abstract, so instances of it cannot be created.

The BaseLayoutItem class also serves as an ancestor for layout groups. A layout group is an object that can contain and display other items and groups.

To get the collection of layout items owned by the LayoutControl control, use the LayoutControl.Items property.

The following code snippets (auto-collected from DevExpress Examples) contain references to the BaseLayoutItem class.
