一、DataTemplate

在WPF（Windows Presentation Foundation）中，DataTemplate 用于定义数据的可视化呈现方式。它允许你自定义如何展示数据对象，从而实现更灵活和丰富的用户界面。DataTemplate 通常用于控件（如ListBox、ComboBox、DataGrid等）的项模板。

1.代码示例

1.1 xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Collections.ObjectModel;namespace 学习
{public partial class MainWindow : Window{public MainWindow(){InitializeComponent();List<Color> test = new List<Color>();test.Add(new Color() { Code = "Red", Name = "红色" });test.Add(new Color() { Code = "BLUE", Name = "蓝色" });test.Add(new Color() { Code = "YELLOW", Name = "黄色" });test.Add(new Color() { Code = "GREEN", Name = "绿色" });list.ItemsSource = test;}}public class Color{public string Code { get; set; }public string Name { get; set; }}
}

1.2 xaml

<Window x:Class="学习.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:学习"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><ListBox x:Name="list"><ListBox.ItemTemplate><DataTemplate><StackPanel Orientation="Horizontal"><Border Width="10" Height="10"Background="{Binding Code}"></Border><TextBlock Margin="10,0" Text="{Binding Name}"></TextBlock></StackPanel></DataTemplate></ListBox.ItemTemplate></ListBox></Grid>
