数据绑定（五）使用集合对象作为列表控件的ItemsSource (转)

ItemsSource属性可以接收一个IEnumerable接口派生类的实例作为自己的值，ItemsSource里存放的是一条一条的数据，列表式控件的条目容器会为这些数据传上外衣，只要为ItemsControl对象设置了ItemsSource属性值，ItemsControl对象就会自动迭代其中的数据元素，为每一个数据元素准备一个条目容器，并使用Binding在条目容器与数据元素之间建立起关联，例子：

界面代码：

 

<StackPanel Background="LightBlue">
    <TextBlock Text="Student ID:" FontWeight="Bold"></TextBlock>
    <TextBox x:Name="textBox1"></TextBox>
    <TextBlock Text="Student List:" FontWeight="Bold"></TextBlock>
    <ListBox x:Name="listBoxStudents" Height="110"></ListBox>
</StackPanel>

<StackPanel Background="LightBlue"> <TextBlock Text="Student ID:" FontWeight="Bold"></TextBlock> <TextBox x:Name="textBox1"></TextBox> <TextBlock Text="Student List:" FontWeight="Bold"></TextBlock> <ListBox x:Name="listBoxStudents" Height="110"></ListBox> </StackPanel>
后台代码：

 

 

public MainWindow()
{
    InitializeComponent();

    List<Student> stuList = new List<Student>()
    {
        new Student(){Id=0, Name="daijun", Age=11},
        new Student(){Id=1, Name="Tim", Age=12},
        new Student(){Id=2, Name="Tom", Age=13},
        new Student(){Id=3, Name="Kyle", Age=14},
        new Student(){Id=4, Name="Tony", Age=15}
    };

    listBoxStudents.ItemsSource = stuList;
    listBoxStudents.DisplayMemberPath = "Name";
    Binding binding = new Binding();
    binding.Source = listBoxStudents;
    binding.Path = new PropertyPath("SelectedItem.Id");
    textBox1.SetBinding(TextBox.TextProperty, binding);
}

public MainWindow() { InitializeComponent(); List<Student> stuList = new List<Student>() { new Student(){Id=0, Name="daijun", Age=11}, new Student(){Id=1, Name="Tim", Age=12}, new Student(){Id=2, Name="Tom", Age=13}, new Student(){Id=3, Name="Kyle", Age=14}, new Student(){Id=4, Name="Tony", Age=15} }; listBoxStudents.ItemsSource = stuList; listBoxStudents.DisplayMemberPath = "Name"; Binding binding = new Binding(); binding.Source = listBoxStudents; binding.Path = new PropertyPath("SelectedItem.Id"); textBox1.SetBinding(TextBox.TextProperty, binding); }
