在WPF中动态添加行到gridview

Question

请帮助我编写以下代码，我想将用户输入的行添加到网格视图中。 我可以添加一行，但它是空的！请帮忙。它可以在 Windows 窗体中运行，但不能在 WPF 中运行。

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;

     }

/////////////////////////// 当然，就是这里

编辑：您绑定了 DataGrid 的 ItemsSource，在这种情况下您无法将项目添加到网格本身，将项目添加到绑定的集合（这是我最初建议的）

我不会建议您做类似的事情。在 WPF 中，您应该 绑定您的控件到数据，这样您就可以更改源集合，并且网格将自动更新，这比使用任何接受 类型的输入的方法（例如 DataGrid.Items.Add ）更简洁对象。

例如
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?"));
    }
