XAML

     <dx:ThemedWindow.Resources>
        <DataTemplate  x:Key="timeRegionTextContentTemplate">
            <TextBlock Text="Break" VerticalAlignment="Center" HorizontalAlignment="Center"/>
        </DataTemplate>
        <DataTemplate  x:Key="timeRegionImageContentTemplate">
            <Image MaxHeight="28"
            Source="{dx:SvgImageSource Uri='pack://application:,,,/DevExpress.Images.v21.2;component/SvgImages/Icon Builder/Travel_Restaurant.svg'}" />
        </DataTemplate>
        <local:TimeRegionTemplateSelector x:Key="timeRegionTemplateSelector"
                                          TimeRegionTextContentTemplate="{StaticResource timeRegionTextContentTemplate}"
                                          TimeRegionImageContentTemplate="{StaticResource timeRegionImageContentTemplate}"/>
    </dx:ThemedWindow.Resources>
    ...
    <dxsch:SchedulerControl>
        <dxsch:SchedulerControl.TimeRegionItems>
            <dxsch:TimeRegionItem Start="{x:Static sys:DateTime.Today}" End="{x:Static sys:DateTime.Now}"
                                  BrushName="{x:Static dxsch:DefaultBrushNames.TimeRegion1Hatch}"
                                  />
        </dxsch:SchedulerControl.TimeRegionItems>
        <dxsch:DayView TimeRegionContentTemplateSelector="{StaticResource timeRegionTemplateSelector}" />
    </dxsch:SchedulerControl>

C#

public class TimeRegionTemplateSelector : DataTemplateSelector {
    public DataTemplate TimeRegionTextContentTemplate { get; set; }
    public DataTemplate TimeRegionImageContentTemplate { get; set; }

    public override DataTemplate SelectTemplate(object item, DependencyObject container) {
        TimeRegionViewModel timeRegion = item as TimeRegionViewModel;
        if (timeRegion != null)
            return (timeRegion.TimeRegion.Start.Hour > 18) ? TimeRegionImageContentTemplate : TimeRegionTextContentTemplate;
        return base.SelectTemplate(item, container);
    }
}

VB.NET

Public Class TimeRegionTemplateSelector
  Inherits DataTemplateSelector

  Public Property TimeRegionTextContentTemplate() As DataTemplate
  Public Property TimeRegionImageContentTemplate() As DataTemplate

  Public Overrides Function SelectTemplate(ByVal item As Object, ByVal container As DependencyObject) As DataTemplate
    Dim timeRegion As TimeRegionViewModel = TryCast(item, TimeRegionViewModel)
    If timeRegion IsNot Nothing Then
      Return If(timeRegion.TimeRegion.Start.Hour > 18, TimeRegionImageContentTemplate, TimeRegionTextContentTemplate)
    End If
    Return MyBase.SelectTemplate(item, container)
  End Function
