Namespace: DevExpress.Xpf.Core

Assembly: DevExpress.Xpf.Core.v20.2.dll


public StyleSelector HeaderItemContainerStyleSelector { get; set; }

Property Value

Type Description

A StyleSelector descendant that chooses a style based on custom logic.


The ThemedWindow.HeaderItemContainerStyle property defines the header items’ style. If you have more than one style that can be used to render property descriptions, you can implement custom logic to choose the required style. To do this, derive from the StyleSelector class, implement the SelectStyle method that returns the style which meets the required condition, and assign it to the HeaderItemContainerStyleSelector property.

If both the ThemedWindow.HeaderItemContainerStyle and HeaderItemContainerStyleSelector are specified, a property description is rendered using the style returned by the style selector. If the template selector returns null, a header item uses the style specified by the ThemedWindow.HeaderItemContainerStyle property.

The following code sample shows how to use the HeaderItemContainerStyleSelector:


      <Style x:Key="editorStyle" TargetType="{x:Type dxe:TextEdit}">
          <Setter Property="MinWidth" Value="50"/>
          <Setter Property="NullText" Value="Search"/>
      <Style x:Key="borderedHeaderItemStyle" TargetType="{x:Type dx:HeaderItemControl}">
          <Setter Property="ShowBorder" Value="False"/>

      <dx:HeaderItemControl Content="DX HeaderItemControl" Tag="borderless"/>
      <dx:HeaderItemControl Content="DX HeaderItemControl" Tag="bordered"/>
      <dxe:TextEdit />
