将行添加到数据网格时，C#WPF抛出System.InvalidOperationException

我有一个WPF数据网格，希望用代码向其中添加数据

XAML：

XAML.cs：

WareneingangEinbuchenGrid.Items.Add(new WareneingangGridData { Name = "Testname", Stueckzahl = 2, Preis = 12.3 , Barcode = "TestBarcode" });

---

执行XAML.CS时，应用程序抛出System.InvalidOperationException错误。

找到解决方案，我编辑了XAML.CS：

Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
        {
            WareneingangEinbuchenGrid.Items.Add(new WareneingangGridData { Name = "Testname", Stueckzahl = 2, Preis = 12.3, Barcode = "TestBarcode" });
        }));

我觉得不错。除了您可能应该设置ItemSource之外。而不是项目。添加

WareneingangEinbuchenGrid.Items.Add(new WareneingangGridData { Name = "Testname", Stueckzahl = 2, Preis = 12.3 , Barcode = "TestBarcode" });

Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
        {
            WareneingangEinbuchenGrid.Items.Add(new WareneingangGridData { Name = "Testname", Stueckzahl = 2, Preis = 12.3, Barcode = "TestBarcode" });
        }));
