【问题描述】：

在运行时，用户无法在我的 wpf 数据网格上添加新的空行。我试过 CanUserAddRow="True", IsReadOnly="False"

XAML

<DataGrid x:Name="UrunGrid" Grid.Row="0" CanUserAddRows="True" AlternatingRowBackground="LightGray" AlternationCount = "2" AutomationProperties.IsOffscreenBehavior="Offscreen">
            <DataGrid.Columns>
                <DataGridTextColumn Header="ISBN/Barkod" Binding="{Binding BARCODE}"/>
                <DataGridTextColumn Header="Ürün Açıklaması" Binding="{Binding PRODUCT_NAME}"/>
                <DataGridTextColumn Header="Adet" Binding="{Binding QUANTITY}"/>
                <DataGridTextColumn Header="ISK" Binding="{Binding DISCOUNT}"/>
                <DataGridTextColumn Header="KDV" Binding="{Binding TAX}"/>
                <DataGridTextColumn Header="Birim Fiyat" Binding="{Binding PURCHASE_PRICE}"/>
                <DataGridTextColumn Header="Tutar" Binding="{Binding AMOUNT}"/>
            </DataGrid.Columns>
        </DataGrid>

类

    class Invoice
{
    public Int64 BARCODE { get; set; }
    public string PRODUCT_NAME { get; set; }

    public int  QUANTITY{ get; set; }

    public int  DISCOUNT{ get; set; }

    public int TAX{ get; set; }

    public int PURCHASE_PRICE { get; set; }

    public int AMOUNT { get; set; }

    public static ObservableCollection<Invoice> getInvoice()
    {
        var invoice = new ObservableCollection<Invoice>();
        return invoice;
    }

}

XAML.CS

public partial class PurchaseInvoice : Page
{

    private const Visibility visible = Visibility.Visible;
    SqlDataReader dataReader;

    public string cariadi { get; private set; }

    public PurchaseInvoice()
    {
        InitializeComponent();
        DataContext = Invoice.getInvoice();

    }

}

我想要；用户可以在此数据网格面板上创建新发票。每行代表一个产品。还有，用户如何用箭头键控制数据网格？

感谢您的回复。

【解决方案1】：

将DataGrid的ItemsSource属性设置或绑定到ObservableCollection<T>：

<DataGrid x:Name="UrunGrid" ItemsSource="{Binding}" ...

或者：

UrunGrid.ItemsSource = Invoice.getInvoice();
