数据绑定(五)使用集合对象作为列表控件的ItemsSource
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>
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);
- }
