Gallery.AllowFilter Property

Gets or sets whether the group filtering feature is enabled. This is a dependency property.

Namespace: DevExpress.Xpf.Bars

Assembly: DevExpress.Xpf.Core.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public bool AllowFilter { get; set; }

VB.NET

Public Property AllowFilter As Boolean

Property Value

Type	Description
Boolean	true if the group filtering feature is enabled; otherwise, false.

Remarks

If the AllowFilter property is set to true the gallery group filtering feature is enabled. In this mode, when a dropdown gallery contains two or more groups the Group Filter panel is displayed at the top of the dropdown gallery. When this panel is clicked, a Group Filter menu is opened, which by default, contains check boxes that correspond to the existing gallery groups and which control the visibility of the groups. Unchecking a check box hides a corresponding group; checking the check box makes the group visible.

The caption of the Group Filter panel is specified by the Gallery.FilterCaption property.
