Question

我是新开发人员，正在练习，创建一个WPF程序以用于一个自助餐厅的点销售，但是，我不知道UserControl在WindowsMain XAML中如何填充Datagrid。我添加了名称x：Name =“ dgSales”，但是从用户控件中我收到此错误消息错误1名称'dgSales'在当前上下文中不存在H：\ WPF Ed \ Cafeteria \ Cafeteria \ Desayuno.xaml.cs < / p>

XAML代码主窗口

public partial class Desayuno : UserControl
{
    public Desayuno()
    {
        InitializeComponent();
    }

    public void ListView_MouseDoubleClick_1(object sender, RoutedEventArgs e)
    {
     //   MessageBox.Show("You clicked me at ");
        List<ventas> venta = new List<ventas>();
        venta.Add(new ventas() { Articulo = "Huevo con Frijoles", Precio = 10, Cantidad = 1, total = 20, Comentarios = "Muy bueno" });
        dgSales.ItemsSource = venta;           

    }
}
