ListBoxEditSettings.GroupStyle Property

Gets a collection of System.Windows.Controls.GroupStyle objects that define the appearance of each level of groups.

Namespace:DevExpress.Xpf.Editors.Settings
Assembly:DevExpress.Xpf.Core.v17.1.dll

Expanded Syntax

Property value

Type: ObservableCollection<GroupStyle>
One or more System.Windows.Controls.GroupStyle objects.

Expanded Remarks

DevExpress WPF ComboBoxEdit, LookUpEdit and ListBoxEdit controls include support for System.ComponentModel.ICollectionView – allowing you to manipulate the current record and define rules for filtering, sorting and grouping.

By default, if a grouping rule is defined in the System.ComponentModel.ICollectionView, editors display the plain list in which items are sorted to accomplish data grouping. Use the GroupStyle property to visually enhance the presentation of grouped items. For instance, you can display expandable groups (see the image below):
