Install TextSearch.Text for WPF-ComboBoxItem using DataTemplate

Question

I use a datatemplate to render some elements in a ComboBox, ItemsSource is bound to an ObservableCollection. To keep it simple, let me say that I put people in an ObservableCollection:

public class Person {
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

My DataTemplate looks like this:

<DataTemplate TargetType="{x:Type Person}">
  <StackPanel Orientation="Horizontal">
    <TextSearch.Text>
      <MultiBinding StringFormat="{} {0} {1}">
        <Binding Path="FirstName"/>
        <Binding Path="LastName"/>
      </MultiBinding>
    </TextSearch.Text>
    <TextBlock Text="{Binding FirstName}" Margin="2,0" />
    <TextBlock Text="{Binding LastName}"/>
  </StackPanel>
</DataTemplate>

ComboBox, person. , TextSearch.TextPath ComboBox, TextSearch.Text-Property ComboBoxItem DataTemplate. , ( MultiBinding StringFormat, Snoop), StackPanel, , Snoop ( ), , , ComboBoxItemTemplate, .. , , ComboBoxItem StackPanel. TextSearch.Text , ComboBoxItem, - .
