WPF基础入门

Class3：WPF数据模板

1、先在cs文件中定义一些数据

cs 复制代码

public partial class Class_4 : Window
    {
        public Class_4()
        {
            InitializeComponent();
            List<Color> test = new List<Color>();
            test.Add(new Color() { Code = "Yellow", Name = "Red" });
            test.Add(new Color() { Code = "#00FF00", Name = "Green" });
            test.Add(new Color() { Code = "#0000FF", Name = "Blue" });
            //数据绑定到list
            list.ItemsSource = test;
        }
    }
    public class Color
    {
        public string Code { get; set;}

        public string Name { get; set; }
    }

2、xaml中编写模板

xml 复制代码

<Grid>
        <!--WPF数据模板-->
        <ListBox x:Name="list">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <!--通过Binding绑定了Background和Text 不用再业务代码cs中穿插控件操作-->
                        <Border
                            Width="10"
                            Height="10"
                            Background="{Binding Code}"></Border>
                        <TextBlock Margin="10, 0" Text="{Binding Name}"></TextBlock>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
</Grid>
