DevExpress Silverlight Chart Scatter 鼠标点击事件

Question

用的是DevExpress Silverlight ChartControl控件

private void mScatter_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
FrameworkElement fe = e.OriginalSource as FrameworkElement;
if (fe == null) return;
SeriesPointPresentationData data = fe.DataContext as SeriesPointPresentationData;
if (data == null) return;

        MessageBox.Show(data.LabelText);
    }

绑定到mScatter里的数据源
TestModel[] datas=this.GetTestModel();
this.mScatter.DataSource=datas;

我需要在鼠标点击是取到原始的TestModel对象，那问高手能指教下，不胜感激。。。
