'Declaration Public Class GroupByAreaFieldLabel Inherits System.Windows.Controls.Primitives.Thumb
public class GroupByAreaFieldLabel : System.Windows.Controls.Primitives.Thumb
GroupByAreaFieldLabel is derived from System.Windows.Controls.Primitives.Thumb and represents a Field in the DataPresenterBase.DefaultFieldLayout. The default style for the GroupByArea contains a System.Windows.Controls.ListBox which is bound to a collection of GroupByAreaFieldLabels. Since the elements in the collection are derived from System.Windows.Controls.Primitives.Thumb they automatically support drag and drop. When the GroupByArea creates these elements it listens to the drag events and automatically groups/ungroups the field represented by the GroupByAreaFieldLabel being dragged.
Note: GroupByAreaFieldLabels are automatically created by the GroupByArea when needed. They are not intended for use outside of these controls and you should never need to create one directly.
