Answer 1

假设你有一个DataGrid，一个文本框和一个按钮，你在XAML窗口，在代码隐藏：

ObservableCollection<string> list = new ObservableCollection<string>(); 
    public Window() 
    { 
     InitializeComponent(); 
     datagrid1.ItemsSource = list; 

    } 
    private void button1_Click(object sender, RoutedEventArgs e) 
    { 
     list.Add(textBox1.Text); 
    } 

Answer 2

你对你的DataGrid到的ObservableCollection的的ItemsSource绑定。 然后，如果你点击按钮只是做那样的事情

myitemssource.add（new myitemtype（））;

在一个非常简单的情况下

：

public partial class TestWindow : Window 
{ 
    public TestWindow() 
    { 
     InitializeComponent(); 
     DataContext = this; 
    } 

    ObservableCollection<Person> _persons; 
    public ObservableCollection<Person> Persons 
    { 
     get { return _persons ?? (_persons = new ObservableCollection<Person>()); } 
     set { _persons = value; } 
    } 

    private void Button_Click(object sender, RoutedEventArgs e) 
    { 
     var split = txtBox.Text.Split(' '); 
     try 
     { 
      Persons.Add(new Person() { FirstName = split[0], LastName = split[1], Age = Int32.Parse(split[2]) }); 
     } 
     catch (IndexOutOfRangeException) 
     { 
     } 
     catch (FormatException) 
     { 
     } 
    } 
} 

public class Person 
{ 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
    public int Age { get; set; } 
}
