如何在WPF中启用组合框的自由文本

Question

如何在WPF中启用组合框的自由文本输入？我尝试使用IsEditable ="True",但即使这样也行不通......

我的xaml语法是: <ComboBox SelectedValue="{Binding Path=CountryValue, Mode=TwoWay}" IsEditable="True" ItemsSource="{Binding Path=CountryValues, Mode=OneWay}"></ComboBox>

    Title="LearnWPF.EditableComboBox" Height="300" Width="300"
    >
  <Window.Resources>
    <XmlDataProvider x:Key="items" XPath="//item">
      <x:XData>
        <items >
          <item>01</item>
          <item>02</item>
          <item>03</item>
        </items>
      </x:XData>
    </XmlDataProvider>
  </Window.Resources>
    <Grid>
      <ComboBox IsEditable="True" DataContext="{StaticResource items}"
                ItemsSource="{Binding}"/>
    </Grid>
</Window>
