<object IsSynchronizedWithCurrentItem="Boolean"/>- or -<object IsSynchronizedWithCurrentItem="{x:Null}"/>

Property Value

Type: System.Nullable<Boolean>
true if the SelectedItem is always synchronized with the current item in the ItemCollection; false if the SelectedItem is never synchronized with the current item; null if the SelectedItem is synchronized with the current item only if the Selector uses a CollectionView. The default value is null.

Identifier field

IsSynchronizedWithCurrentItemProperty

Metadata properties set to true

None

You can set the IsSynchronizedWithCurrentItem property to true to ensure that the item selected always corresponds to the CurrentItem property in the ItemCollection. For example, suppose that there are two ListBox controls with their ItemsSource property set to the same source. Set IsSynchronizedWithCurrentItem to true on both list boxes to ensure that the selected item in each ListBox is the same.

The following example binds two ListBox controls to the same ItemsSource. Because IsSynchronizedWithCurrentItem is set to true on each ListBox, the selected item is always the same for both controls

<XmlDataProvider x:Key="Employees" XPath="/Employees/*">
  <x:XData>
    <Employees xmlns="">
      <Employee Name="Terry Adams" Type="FTE" EmployeeNumber="1" />
      <Employee Name="Claire O&apos;Donnell" Type="FTE" EmployeeNumber="12345" />
      <Employee Name="Palle Peterson" Type="FTE" EmployeeNumber="5678" />
      <Employee Name="Amy E. Alberts" Type="CSG" EmployeeNumber="99222" />
      <Employee Name="Stefan Hesse" Type="Vendor" EmployeeNumber="-" />
    </Employees>
  </x:XData>
</XmlDataProvider>

<DataTemplate x:Key="EmployeeItemTemplate">
  <TextBlock Text="{Binding XPath=@Name}" />
</DataTemplate>

<ListBox Name="employeeListBox1"
         ItemsSource="{Binding Source={StaticResource Employees}}"
         ItemTemplate="{StaticResource EmployeeItemTemplate}"
         IsSynchronizedWithCurrentItem="True"/>

<ListBox Name="employeeListBox2"

         IsSynchronizedWithCurrentItem="True"/>
