无法在UserControl中将ObservableCollection绑定到DataGrid

<DataGrid ItemsSource="{Binding YourObservableCollection}" />

public partial class YourUserControl : UserControl
{
    public YourUserControl()
    {
        InitializeComponent();
        DataContext = new YourViewModel(); // 替换为你自己的ViewModel实例
    }
}

public class YourViewModel : INotifyPropertyChanged
{
    private ObservableCollection<YourDataItem> yourObservableCollection;

    public YourViewModel()
    {
        YourObservableCollection = new ObservableCollection<YourDataItem>();
        // 在这里添加数据到ObservableCollection
    }

    public ObservableCollection<YourDataItem> YourObservableCollection
    {
        get { return yourObservableCollection; }
        set
        {
            yourObservableCollection = value;
            OnPropertyChanged(nameof(YourObservableCollection));
        }
    }

    // 实现INotifyPropertyChanged接口
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

public class YourDataItem
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
    // 添加更多属性...
}
