Question

我一直在研究如何将GridView绑定到ObservableCollection。所有示例都执行相同的步骤，但它不适用于我的应用程序。

我甚至在这里复制了这个例子：http://www.switchonthecode.com/tutorials/wpf-tutorial-using-the-listview-part-1

在声明XAML中的项目时，DisplayMemberBinding正在工作，因此问题必须是集合。

对于XAML：

<ListView ItemsSource="{Binding GameCollection}" Margin="0,123,0,41">
        <ListView.View>
            <GridView>
                <GridViewColumn Width="140" Header="Game Name" 
         DisplayMemberBinding="{Binding GameName}"  />
                <GridViewColumn Width="140" Header="Creator"  
         DisplayMemberBinding="{Binding Creator}" />
                <GridViewColumn Width="140" Header="Publisher" 
         DisplayMemberBinding="{Binding Publisher}" />
            </GridView>
        </ListView.View>
    </ListView>

对于CS

public partial class MainWindow : Window
{
    ObservableCollection<GameData> _GameCollection =
    new ObservableCollection<GameData>();


    public MainWindow()
    {
        _GameCollection.Add(new GameData
        {
            GameName = "World Of Warcraft",
            Creator = "Blizzard",
            Publisher = "Blizzard"
        });
        _GameCollection.Add(new GameData
        {
            GameName = "Halo",
            Creator = "Bungie",
            Publisher = "Microsoft"
        });
        _GameCollection.Add(new GameData
        {
            GameName = "Gears Of War",
            Creator = "Epic",
            Publisher = "Microsoft"
        });


        InitializeComponent();
        Focus();
    }


    public ObservableCollection<GameData> GameCollection
    { get { return _GameCollection; } }
}

public class GameData
{
    public string GameName { get; set; }
    public string Creator { get; set; }
    public string Publisher { get; set; }
}

Answer 1

您的绑定不会在您的表单上找到该属性。您没有指定查找GameCollection的位置：绑定不知道在哪里查找。

将x:Name="someName"添加到窗口的根元素，然后将绑定修改为{Binding GameCollection, ElementName=someName}。这将解决绑定问题。

Answer 2

实际上你需要做的就是确保正确设置datacontext

DataContext =“{Binding RelativeSource = {RelativeSource Self}}”将其放入窗口的标记中。

WPF GridView没有绑定到集合
