Collectionviewsource Datagrid WPF MVVM不显示行

Question

我是WPF和MVVM的新手。我试图在我的项目中使用Datagrid和Collectionviewsource。我已经达到了以下某个级别，但我的Datagrid没有显示任何行。下面是代码部分。我想弄清楚我在这里缺少什么。请注意，我只发布此问题所必需的代码部分。

ScanBatchWindow.xaml.cs

public partial class ScanBatchWindow : Window
{
    public ScanBatchWindow()
    {
        InitializeComponent();
        ScanBatchViewModel pMV = new ScanBatchViewModel();
        this.DataContext = pMV;
    }
}

ScanBatchWindow.xaml

<Window x:Class="BatchManPOC.ScanBatchWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</Window.Resources>
     <Grid>
         <Grid.RowDefinitions>
               <RowDefinition/>
         </Grid.RowDefinitions>
              <Custom:DataGrid ItemsSource="{Binding Source={StaticResource CVS}}" Margin="8" Grid.Row="0" AutoGenerateColumns="True"  IsReadOnly="True">
</Custom:DataGrid>
        </Grid>
</Window>

ScanBatchViewModel.cs

请注意，我有 BaseViewModel ，它继承自 INotifyPropertyChanged 。

    public class ScanBatchViewModel : BaseViewModel
    {
        public CollectionViewSource CVS { get; set; }
        public ObservableCollection<Batch> p_ListBatches { get; set; }

        public class Batch
        {
            public DateTime p_dCreated;
            public int p_iReference;
            public BatchStatus p_iBatchStatus;
            public string p_sFromBranch;
        }

        /// <summary>
        /// Initializes a new instance of the ScanBatchViewModel class.
        /// </summary>
        public ScanBatchViewModel()
        {
            LoadBatches();
            CVS = new CollectionViewSource();
        }

        public void LoadBatches()
        {
            //Add sample objects
            p_ListBatches.Add(new Batch() { p_dCreated = DateTime.Now, p_iBatchStatus = BatchStatus.DOC_STATUS_CREATED, p_iReference = 1, p_sFromBranch = "7010888" });
            p_ListBatches.Add(new Batch() { p_dCreated = DateTime.Now, p_iBatchStatus = BatchStatus.DOC_STATUS_DELETED, p_iReference = 2, p_sFromBranch = "7010999" });
            p_ListBatches.Add(new Batch() { p_dCreated = DateTime.Now, p_iBatchStatus = BatchStatus.DOC_STATUS_RECEIVED, p_iReference = 3, p_sFromBranch = "7010000" });
            p_ListBatches.Add(new Batch() { p_dCreated = DateTime.Now, p_iBatchStatus = BatchStatus.DOC_STATUS_SENT, p_iReference = 4, p_sFromBranch = "7010777" });
        }
    }

Answer 1

谢谢，我找到了答案。我没有将批次类的成员定义为属性。因此，虽然我们将值设置为公共成员，但它们不会出现在.XAML中，因为它们不作为属性公开。如下更改它们对我有用。

public class Batch
{
    public DateTime p_dCreated { get; set; }
    public int p_iReference { get; set; }
    public BatchStatus p_iBatchStatus { get; set; }
    public string p_sFromBranch { get; set; }
}
