如何在WPF中的选项卡控件中将选定值路径设置为选项卡标题文本

Question

我对如何将TabControl的SelectedValuePath设置为所选TabItems标题的文本有点不清楚。我觉得这应该是相当简单的，可能涉及content.something但我总是对Content属性有点困惑。

ItemTemplate - 标签标题的模板。只需添加具有与属性SelectedValuePath相同的绑定的文本块。

<UserControl.Resources>
    <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="HeaderDataTemplate">
        <TextBlock Text="{Binding XPath=@EmployeeNumber}" />
    </DataTemplate>
    <DataTemplate x:Key="ContentDataTemplate">
        <TextBlock Text="{Binding XPath=@Name}" />
    </DataTemplate>
</UserControl.Resources>

<TabControl ItemsSource="{Binding Source={StaticResource Employees}}"
         ItemTemplate="{StaticResource HeaderDataTemplate}"
         ContentTemplate="{StaticResource ContentDataTemplate}"
         SelectedValue="12345"
         SelectedValuePath="@EmployeeNumber"/>
