将附加列与数据网格WPF中的任何控件绑定

使用时 WPF 遵循 MVVM 图案无论哪种方式,您都应该为您的 Order (包含Id、名称、数量等属性…)。此类还应具有 Aditionals (例如 strings ). 然后使用适当的 DataBindings 您将实现所需的功能。

这是一个很好的例子,可以给你一个想法:

订单类别:

public class Order : INotifyPropertyChanged
{
    #region INotifyPropertyChanged
    public event PropertyChangedEventHandler PropertyChanged;

    void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
    #endregion

    public Order(int id)
    {
        DBDataContext dbContext = new DBDataContext();
        DCAPPDBDataContext dbContext2 = new DCAPPDBDataContext();

        var itemsSource = dbContext.SP_Get_ItemList(id);
        var additionals = dbContext2.SP_Get_AdditionalsList(id);

        Id = id;
        Name = itemsSource.name;
        Quantity = itemsSource.quantity;
        // other properties ...

        Additionals = new ObservableCollection<string>();
        foreach (var item in additionals)
        {
            Additionals.Add(item);
        }
    }

    private int _id;
    public int Id
    {
        get
        {
            return _id;
        }
        set
        {
            _id = value;
            OnPropertyChanged("Id");
        }
    }

    // define other properties e.g. Name, Quantity, Price, etc.
    // the same way as Id.

    public ObservableCollection<string> Additionals {get;set;}
}

Xaml:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <DataGrid Grid.Row="0" AutoGenerateColumns="False"
          ItemsSource="{Binding Orders}" 
          SelectedItem="{Binding SelectedOrder}">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Item ID" Binding="{Binding Id}" />
        <DataGridTextColumn Header="Item Name" Binding="{Binding Name}" />
        <DataGridTemplateColumn Header="Addtionals">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                        <ItemsControl ItemsSource="{Binding Additionals}">
                            <ItemsControl.ItemTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding}"/>
                                </DataTemplate>
                            </ItemsControl.ItemTemplate>
                        </ItemsControl>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTextColumn Header="Quantity" Binding="{Binding Quantity}" />
        <DataGridTextColumn Header="Item Price" Binding="{Binding Price}" />
    </DataGrid.Columns>
</DataGrid>
<Button  Grid.Row="1" Content="New Order" Click="Order_Click"/>
</Grid>

主窗口.cs:

    public ObservableCollection<Order> Orders { get; set; }

    public Order SelectedOrder { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        DataContext = this;

        Orders = new ObservableCollection<Order>();

    }

    private void Order_Click(object sender, RoutedEventArgs e)
    {
        SP_Get_OrderItemResult orderRow = gridOrder.SelectedItem as SP_Get_OrderItemResult;
        Orders.Add(new Order(orderRow.orderid));
    }

在Bahman_Aries的帖子和一些小东西的帮助下,我发布了准确的解决方案。 这正是我想要的解决方案。

订单类别:

public class Order : INotifyPropertyChanged
{
    #region INotifyPropertyChanged
    public event PropertyChangedEventHandler PropertyChanged;

    void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
    #endregion

    public Order(SP_Get_ItemListResult itemResult)
    {
        DBDataContext dbContext = new DBDataContext();                


         orderItemID = itemResult.orderItemID;
        itemName = itemResult.ItemName;
        quantity = itemResult.quantity;           
        // other properties ...

      var additionals = dbContext.SP_Get_AdditionalsList(orderItemID);

        Additionals = new ObservableCollection<string>();
        foreach (var item in additionals)
        {
            Additionals.Add(item.Additionals);
        }
    }

    private int _id;
    public int Id
    {
        get
        {
            return _id;
        }
        set
        {
            _id = value;
            OnPropertyChanged("Id");
        }
    }

    // define other properties e.g. Name, Quantity, Price, etc.
    // the same way as Id.

    public ObservableCollection<string> Additionals {get;set;}
}

XAML代码中没有更改。

主窗口.cs:

public ObservableCollection<Order> Orders { get; set; }

public Order SelectedOrder { get; set; }

public MainWindow()
{
    InitializeComponent();
    DataContext = this;

    Orders = new ObservableCollection<Order>();

}

private void Order_Click(object sender, RoutedEventArgs e)
{
    SP_Get_OrderItemResult orderRow = gridOrder.SelectedItem as SP_Get_OrderItemResult;
      List<SP_Get_ItemListResult> itemsSource = dbContext.SP_Get_ItemList(orderRow.orderid).ToList();
            for (int i = 0; i < itemsSource.Count(); i++)
            {
                Orders.Add(new Order(itemsSource[i]));
            }         
}
