【WPF】Combox 下拉选项增加图片显示 ItemTemplate

 效果图如上所示：

前端Xmal代码：

<Window x:Class="WpfTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfTest"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <StackPanel>
            <Button Content="www.wikibt.com"  Click="Button_Click"></Button>

            <ComboBox ItemsSource="{Binding Items}" SelectedItem="{Binding CurrentItem}">
                <ComboBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <Image Source="/images/www.wikibt.com.png"></Image>//此处图片路径写死了,可以用绑定实现不一样的图片{Binding ItemImage}
                            <TextBlock Text="{Binding ItemName}" VerticalAlignment="Center" HorizontalAlignment="Center"></TextBlock>
                        </StackPanel>
                    </DataTemplate>
                </ComboBox.ItemTemplate>
            </ComboBox>
        </StackPanel>
    </Grid>
</Window>

后端代码：

namespace WpfTest
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Items = new List<ImageItem>() {
                new ImageItem("一",1),new ImageItem("二",2),new ImageItem("三",3)
            };
            this.DataContext = this;
        }

        public List<ImageItem> Items { get; set; }
        public ImageItem CurrentItem { get; set; }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(CurrentItem == null ? "null" : CurrentItem.ItemValue.ToString());
        }
    }
    public class ImageItem
    {
        public ImageItem(string name, object value)
        {
            ItemName = name;
            ItemValue = value;
        }
        public ImageItem(string name, object value, ImageSource img) : this(name, value)
        {
            ItemImage = img;
        }
        public string ItemName { get; set; }
        public object ItemValue { get; set; }
        public ImageSource ItemImage { get; set; }
    }
}
