Question

我有一个DataGrid。此DataGrid的ItemsSource在WCF调用的Completed事件中设置。但是，在主网格DataTemplate中添加Detail Datagrid并正确命名时... Ineed填充主网格选择更改事件但我的代码隐藏无法识别细节网格。我不能像使用grdMaster那样设置grdDetail的ItemsSource。所以我如何填充我的详细数据网格？

Xaml文件

  <Grid x:Name="LayoutRoot">

    <sdk:DataGrid x:Name="dgCustList" AutoGenerateColumns="False" Background="Transparent" SelectionChanged="dgCustList_SelectionChanged">
        <sdk:DataGrid.RowDetailsTemplate>
            <DataTemplate>
                <StackPanel x:Name="stkPanel">
                    <sdk:DataGrid x:Name="dgCustDetail" RowDetailsVisibilityMode="VisibleWhenSelected" AutoGenerateColumns="False"  Background="Transparent"/>
                </StackPanel>
            </DataTemplate>
        </sdk:DataGrid.RowDetailsTemplate>
    </sdk:DataGrid>
    <Grid.Projection>
        <PlaneProjection x:Name="Projection"/>
    </Grid.Projection>
</Grid>

和CodeBehind

  public MusteriListe()
    {
        InitializeComponent();
        var stb1 = new Storyboard { Duration = new Duration(TimeSpan.FromSeconds(1)), SpeedRatio = 3 };

        var daY1 = new DoubleAnimation { From = 0.00, To = 90.00 };
        Storyboard.SetTargetName(daY1, "Projection");
        Storyboard.SetTargetProperty(daY1, new PropertyPath("RotationX"));
        stb1.Children.Add(daY1);
        this.Resources.Add("EndOfPage", stb1);

        var stb = new Storyboard();
        stb.Duration = new Duration(TimeSpan.FromSeconds(1));
        stb.SpeedRatio = 3;

        var daY = new DoubleAnimation { From = -90.00, To = 0.00 };
        Storyboard.SetTargetName(daY, "Projection");
        Storyboard.SetTargetProperty(daY, new PropertyPath("RotationX"));
        stb.Children.Add(daY);
        Resources.Add("StartOfPage", stb);

        dgCustList.Columns.Add(new DataGridTextColumn
        {
            Header = "ID",
            Binding = new Binding("CustomerID")
        });
        dgCustList.Columns.Add(new DataGridTextColumn
        {
            Header = "Müşteri Ad",
            Binding = new Binding("CustomerName")
        });
        dgCustList.Columns.Add(new DataGridTextColumn
        {
            Header = "Müşteri Soyad",
            Binding = new Binding("CustomerSurname")
        });
        dgCustList.Columns.Add(new DataGridTextColumn
        {
            Header = "Müşteri Tel",
            Binding = new Binding("CustomerPhone")
        });
        LoadGrid();
    }
    private void LoadGrid()
    {
        var client = new EczServiceClient();
        client.CustomerInfoCompleted += client_CustomerInfoCompleted;
        client.CustomerInfoAsync();
    }
    void client_CustomerInfoCompleted(object sender, CustomerInfoCompletedEventArgs e)
    {
        dgCustList.ItemsSource = e.Result;
    }

    private void dgCustList_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {

        var customer = dgCustList.SelectedItem as CustomerInfo;
        if (customer == null) return;
        var client = new EczServiceClient();
        client.CustomerDetailCompleted += client_CustomerDetailCompleted;
        client.CustomerDetailAsync(customer.CustomerID);

    }
    void client_CustomerDetailCompleted(object sender, CustomerDetailCompletedEventArgs e)
    {
        IN HERE I WANT TO FILL DATAGRID LIKE MASTER GRID BUT ITS NOT LET ME ( dgCustDetail.ItemSource = e.Result)
    }

Answer 1

您没有为详细数据网格定义绑定，并将自动生成列设置为false。在client_CustomerDetailCompleted事件触发之前，您需要在XAML或后面的代码中定义绑定。仅仅设置项目源不起作用，因为详细数据网格不包含列。这是MVVM pattern派上用场的地方。
