Datagrid数据绑定

Question

我有一个绑定到静态ListCollectionView

的数据网格

CompassLogView类：

        public static ListCollectionView Compasscollection {
        get {
            if (_compasscollection == null) {
                _compasscollection =
                    new ListCollectionView(LogSession.CompassLogCollection);
            }
            return _compasscollection;
        }
        set { _compasscollection = value; }
    }

绑定

compassLogDataGrid.DataContext = CompassLogView.Compasscollection;

datagrid Xaml：

        <DataGrid x:Name="compassLogDataGrid"
              ItemsSource="{Binding}"
              SelectionMode="Single"
              IsSynchronizedWithCurrentItem="True"
              SelectedItem="{Binding Path=Synchronizer.CurrentCompassLogDataItem}"
              Style="{DynamicResource ResourceKey=dataGridStyle}">
              ...
</DataGrid>

SelectedItem（第5行）必须绑定到currentCompassLogDataItem类中的Synchronizer。

我试过但似乎不可能。有什么建议吗？

<DataGrid x:Name="compassLogDataGrid"
          ItemsSource="{Binding}"
          SelectionMode="Single"
          IsSynchronizedWithCurrentItem="True"
          SelectedItem="{Binding Path=CurrentCompassLogDataItem,Source={StaticResource synchronizer} }"
          Style="{DynamicResource ResourceKey=dataGridStyle}">
        <DataGrid.Resources>
            <local:Synchronizer x:Key="synchronizer"/>
        </DataGrid.Resources>
    </DataGrid>

local：指定xmlns中的命名空间。我希望这会有所帮助
