Question

I’m using a combobox in my application and I am populating it with classes something like this:

namespace Foo.Bar{
     public class Item
     {
          public string lastName;
          public string firstName;
          public Foo theMeatyPart;
     }
}

I can populate the dropdown with “lastName, firstName” using an itemTamplate but then the selected value shows up as “Foo.Bar.Item”. How can I apply the same template to the selectedItem and also, have the search functionality work without overrriding the ToString method of Item?

Here is the xaml:

<Style x:Key="SearchComboStyle" TargetType="ComboBox">
                <Style.Setters>
                    <Setter Property="Width" Value="150"></Setter>
                </Style.Setters>
            </Style>
            <DataTemplate x:Key="SearchComboItemTemplate" >
                    <TextBlock DataContext="{Binding}">
                            <TextBlock.Text>
                              <MultiBinding StringFormat="{}{0}, {1}">
                                <Binding Path="lastName"/>
                                <Binding Path="firstName"/>
                              </MultiBinding>
                            </TextBlock.Text>
                    </TextBlock>
            </DataTemplate>


<ComboBox  ItemTemplate="{StaticResource SearchComboItemTemplate}" Style="{StaticResource SearchComboStyle}" 
                    ItemsSource="{Binding Path=PhysiciansList, RelativeSource={RelativeSource AncestorType=local:ExamViewerControl, AncestorLevel=1}}"      IsTextSearchEnabled="True" IsTextSearchCaseSensitive="False" IsEditable="True" TextSearch.TextPath="Person.LastName" />

UPD: Looks like you need to set SelectionBoxItemTemplate.

You can use DisplayMemberPath or TextSearch.TextPath to enable search without modifying ToString().
