Restores the current layout item from the Customization Form and adds it to the root group with the default layout type.
public virtual void RestoreFromCustomization()
Public Overridable Sub RestoreFromCustomization
The default layout type is determined by the LayoutGroup.DefaultLayoutType property. By default it is set to LayoutType.Vertical, so the restored layout item is positioned at the bottom of the root group. If this property is set to LayoutType.Horizontal, the layout item is positioned at the root group's right edge.
