我有一个DataGrid,它通过异步方法从ViewModel填充数据.我的DataGrid是:

<DataGrid ItemsSource="{Binding MatchObsCollection}"  x:Name="dataGridParent" 
                      Style="{StaticResource EfesDataGridStyle}" 
                      HorizontalGridLinesBrush="#DADADA" VerticalGridLinesBrush="#DADADA" Cursor="Hand" AutoGenerateColumns="False" 
                      RowDetailsVisibilityMode="Visible"  >

我正在使用http://www.amazedsaint.com/2010/10/asynchronous-delegate-command-for-your.html在我的viewmodel中实现异步方式.

这是我的viewmodel代码:

public class MainWindowViewModel:WorkspaceViewModel,INotifyCollectionChanged
    {        

        MatchBLL matchBLL = new MatchBLL();
        EfesBetServiceReference.EfesBetClient proxy = new EfesBetClient();

        public ICommand DoSomethingCommand { get; set; }
        public MainWindowViewModel()
        {
            DoSomethingCommand = new AsyncDelegateCommand(
                () => Load(), null, null,
                (ex) => Debug.WriteLine(ex.Message));           
            _matchObsCollection = new ObservableCollection<EfesBet.DataContract.GetMatchDetailsDC>();                

        }       

        List<EfesBet.DataContract.GetMatchDetailsDC> matchList;
        ObservableCollection<EfesBet.DataContract.GetMatchDetailsDC> _matchObsCollection;

        public ObservableCollection<EfesBet.DataContract.GetMatchDetailsDC> MatchObsCollection
        {
            get { return _matchObsCollection; }
            set
            {
                _matchObsCollection = value;
                OnPropertyChanged("MatchObsCollection");
            }
        }        
        // …
