I want to bind a observable collection to a grid through xaml

collection is in cs file of xaml1 and grid in xaml2... how do i do it..

推荐答案

您需要通过以下对象上的Public属性使ObservableCollection可用xaml1.然后在xaml2中，您需要对xaml1的引用，您可以通过在xaml2的构造函数中传递xaml1的实例来做到这一点.然后，您可以将DataGrid绑定到集合.这是一个简单的示例(我使用了WPF，但是Silverlight的方法相同)

You need to make the ObservableCollection available via a Public Property on xaml1. Then in xaml2 you need a reference to xaml1, you can do this by passing an instance of xaml1 in the constructor of xaml2. Then you can bind the DataGrid to the Collection. Here is a simple example( I used WPF but the methodology is the same for Silverlight)

public partial class MainWindow: Window
   {
       private ObservableCollection<Person> people;
       public ObservableCollection<Person> People
       {
           get
           {
               return people;
           }
       }
       public MainWindow()
       {
           InitializeComponent();
           people = new ObservableCollection<Person>() {new Person("a"), new Person("b"), new Person("c"), new Person("d"), new Person("e") };
       }
       private void buttonClick(object sender, RoutedEventArgs e)
       {
           Window1 w1 = new Window1(this);
           w1.Show();
       }
   }
   public class Person
   {
       public string Name { get; set; }
       public Person(string name)
       {
           this.Name = name;
       }
   }

这就是如何在第二个窗口中进行绑定

and this is how to bind in the second window

public partial class Window1 : Window
   {
       public Window1(MainWindow mw)
       {
           InitializeComponent();
           dataGrid1.DataContext = mw.People;
           dataGrid1.DisplayMemberPath = "Name";
       }
   }
