Assembly: DevExpress.Xpf.NavBar.v24.2.dll

NuGet Package: DevExpress.Wpf.NavBar

Declaration

C#

public DataTemplateSelector HeaderTemplateSelector { get; set; }

VB.NET

Public Property HeaderTemplateSelector As DataTemplateSelector

Property Value

Type	Description
DataTemplateSelector	A DataTemplateSelector descendant that chooses a template based on custom logic.

Remarks

A template that defines the presentation of group headers is specified by the NavBarViewBase.HeaderTemplate property. If you have more than one template that can be used to render group headers, you can implement custom logic to choose the required template. To do this, derive from the DataTemplateSelector class, implement the SelectTemplate method that returns a template which meets the required condition, and assign it to the HeaderTemplateSelector property.

If both the NavBarViewBase.HeaderTemplate and HeaderTemplateSelector are specified, a group item is rendered using the template returned by the template selector. If the template selector returns null, the template specified by the NavBarViewBase.HeaderTemplate property is used.
