Question

我试图将一些XML数据绑定到DataGrid，代码工作正常，但我无法绑定到属性值。

<DataGrid Name="productGrid"  HorizontalAlignment="Left" Margin="10,66,0,0" VerticalAlignment="Top" Height="459" Width="748" AutoGenerateColumns="false">
        <DataGrid.Columns>
            <DataGridTextColumn Header="ID" Binding="{Binding Path=Element[product].Attribute[id].Value}" />
            <DataGridTextColumn Header="Kategori" Binding="{Binding Path=Element[category].Value}" />
            <DataGridTextColumn Header="Title" Binding="{Binding Path=Element[title].Value}" />
            <DataGridTextColumn Header="Beskrivelse" Binding="{Binding Path=Element[description].Value}" />
            <DataGridTextColumn Header="Pris" Binding="{Binding Path=Element[price].Value}" />
        </DataGrid.Columns>
    </DataGrid>

代码背后：

        public Page1()
    {
        InitializeComponent();

        var xElem = XElement.Load(AppDomain.CurrentDomain.BaseDirectory + @"\\Data\\Products.xml");

        this.defaultView = CollectionViewSource.GetDefaultView(xElem.Elements("product"));
        this.defaultView.Filter = w => ((XElement)w).ToString().Contains(freeText.Text);

        productGrid.ItemsSource = this.defaultView;

    }

    private void SearchProducts(object sender, RoutedEventArgs e)
    {
        // Filter GridView
        this.defaultView.Refresh();
    }

是否可以将列绑定到属性值？如果是这样，怎么样？

是否有一种更优雅的方式来绑定列，可能来自后面的代码？

在这种情况下，您可以从绑定中删除一些额外元素，即Element[product]，这些不是必需的，因为绑定元素是产品本身

例如

<DataGrid Name="productGrid"  HorizontalAlignment="Left" Margin="10,66,0,0" VerticalAlignment="Top" Height="459" Width="748" AutoGenerateColumns="false">
    <DataGrid.Columns>
        <DataGridTextColumn Header="ID" Binding="{Binding Path=Attribute[id].Value}" />
        <DataGridTextColumn Header="Kategori" Binding="{Binding Path=Element[category].Value}" />
        <DataGridTextColumn Header="Title" Binding="{Binding Path=Element[title].Value}" />
        <DataGridTextColumn Header="Beskrivelse" Binding="{Binding Path=Element[description].Value}" />
        <DataGridTextColumn Header="Pris" Binding="{Binding Path=Element[price].Value}" />
    </DataGrid.Columns>
</DataGrid>

WPF将DataGrid绑定到XElement属性值
