如何为自定义用户控件中的ListBox ItemTemplate属性设置适当的上下文

public static readonly DependencyProperty ItemTemplateProperty = DependencyProperty.Register(
    "ItemTemplate", typeof(DataTemplate), typeof(YourCustomControl), new PropertyMetadata(null));

public DataTemplate ItemTemplate
{
    get { return (DataTemplate)GetValue(ItemTemplateProperty); }
    set { SetValue(ItemTemplateProperty, value); }
}

<ListBox ItemTemplate="{Binding ItemTemplate, RelativeSource={RelativeSource AncestorType={x:Type local:YourCustomControl}}}"/>

<local:YourCustomControl>
    <local:YourCustomControl.ItemTemplate>
        <DataTemplate>
            <!-- 在这里定义ListBox中每个项的外观 -->
        </DataTemplate>
    </local:YourCustomControl.ItemTemplate>
</local:YourCustomControl>
