添加行dyanamicaly到WPF的gridview

Question

请帮我用下面的代码，我想添加一行用户输入到一个gridview。 我能够添加一行，但它的空!!请help.it工作在Windows窗体中，但它不与WPF一起工作。

private void button1_Click(object sender, RoutedEventArgs e) 
     { 
      GetGridView(); 
     } 
     private void GetGridView() 
     { 

     string[] row0 = {textBox1.Text,"Beatles" }; 

      dataGrid1.Items.Add(row0); 
      dataGrid1.Columns[0].DisplayIndex = 0; 
      dataGrid1.Columns[1].DisplayIndex = 1; 

    } 

////////////// 肯定的是，在这里它是

<Window x:Class="WpfApplication2.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

      <DataGridTextColumn Header="Header" /> 
     </DataGrid.Columns> 
    </DataGrid> 
    <TextBox Height="23" HorizontalAlignment="Left" Margin="184,12,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" TextChanged="textBox1_TextChanged" />

编辑：您绑定的DataGrid的ItemsSource时，你不能将项目添加到网格本身，而这种情况下，将项目添加到绑定的集合（这是我原来建议的）

我不会建议你做那样的事情。在WPF中，您应该使用bind your controls来处理数据，这样您就可以更改源代码集合，并且网格会自动更新，这比使用接受object类型的输入的任何方法（如DataGrid.Items.Add）要更简洁。

例如
的XAML：

<DataGrid ItemsSource="{Binding GridData}" Name="DGrid"/> 
    <TextBox Name="TB" Width="100"/> 
    <Button Content="Add" Click="Button_Click"/> 

代码：

private ObservableCollection<Employee> gridData = new ObservableCollection<Employee>(); 
    public ObservableCollection<Employee> GridData 
    { 
     get { return gridData; } 
    } 

    private void Button_Click(object sender, RoutedEventArgs e) 
    { 
     GridData.Add(new Employee(TB.Text, "Beatles?")); 
    }
