问题描述

朋友们，请问我有这段代码：

Hello friends,please I have this code:

<DataGrid Name="dgvArticulos"  Width="450" Height="350" AutoGenerateColumns="False" CanUserAddRows="False" >
    <DataGrid.Columns>
           <DataGridTemplateColumn Header="Unidad Medida" Width="100">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <ComboBox  ItemsSource="{Binding ListaUnidades}" SelectedValuePath="Codigo" DisplayMemberPath="Descripcion" SelectedIndex="0" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTextColumn Header="Descripcion" Binding="{Binding Descripcion}" Width="300"  IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>

这是我的代码，它运作良好：

And this is my code,it work well :

public partial class MainWindow : Window
    {
        public class UMedida
        {
            public int Codigo { get; set; }
            public String Descripcion { get; set; }
        }
        public  class CProductos
        {
            public int ID { get; set; }
            public String Descripcion { get; set; }
            public List<UMedida> ListaUnidades { get; set; }
        }
        public ObservableCollection<CProductos> ListaProductos;

        public MainWindow()
        {
            ListaProductos = new ObservableCollection<CProductos>() 
                {
                new CProductos{ ID=3, Descripcion="Producto Uno",ListaUnidades= new List<UMedida>{ new UMedida{Codigo=1,Descripcion="Unidad"},new UMedida{Codigo=1,Descripcion="Pkg x6"}}},

            this.DataContext = ListaProductos;
            InitializeComponent();
            dgvArticulos.ItemsSource = ListaProductos;
        }

我尝试做的是当用户选择一行时我需要知道哪个度量单位被分配了某篇文章

What I try to do is when the user selects a row I need to know what unit of measure is assigned a certain article

private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            CProductos prod = (CProductos)dgvArticulos.SelectedItem;
            prod.ListaUnidades // help me please
        }
