更新:如果第二次在表中有多行,数据将正确显示在文本框中!到底怎么回事?

<Grid Height="165" Width="390" DataContext="{Binding caseTableView}" >

            <Grid.Resources>
                <local:CaseStatusItemsSource x:Key="StatusesSource" />

微软的代码中一定有一个bug,因为我用下面的代码修复了它。

            ICollectionView _cv = CollectionViewSource.GetDefaultView(_appModel.casesTable);
            _cv.MoveCurrentToNext();

我只需要为case表而不是jobs表执行此操作,这就是为什么我希望在某个地方会有一个bug。无论表中有一行还是多行,jobs表都始终有效。
