WPF ListBox ComBox应用DataTemplate 绑定数据

<Window.Resources>
        <DataTemplate x:Key="DefualtTemplate">
            <StackPanel Orientation="Horizontal" >
                <Border  Height="10" Width="10" Background="{Binding ColorCode}"/>
                <TextBlock Text="{Binding ColorCode}"/>
            </StackPanel>
        </DataTemplate>
    </Window.Resources>
定义key为DefualtTemplate的数据模板，使用border元素的背景颜色显示颜色，使用TextBolck显示颜色代码

 <StackPanel Grid.Row="0" Orientation="Vertical"  VerticalAlignment="Center">
            <ComboBox Name="cmb" ItemTemplate="{StaticResource DefualtTemplate}"/>
            <ListBox x:Name="lbox" ItemTemplate="{StaticResource DefualtTemplate}"/>
       
 </StackPanel>
在Combox 和ListBox中绑定ItemTemplate 

 var colors = new List<Color>();
            colors.Add(new Color() { ColorCode = "#FFB6C1" });
            colors.Add(new Color() { ColorCode = "#FFC0CB" });
            colors.Add(new Color() { ColorCode = "#DA70D6" });
            colors.Add(new Color() { ColorCode = "#EE82EE" });
            colors.Add(new Color() { ColorCode = "#FF00FF" });
            this.cmb.ItemsSource = colors;
            this.lbox.ItemsSource = colors;

  public class Color
    {
        public string ColorCode { get; set; }
    }
