部分代码： 

 <dxg:GridControl x:Name="gridControl" ItemsSource="{Binding ChartInfoList}"  SelectedItem="{Binding Path=SelectedChartModel, Mode=TwoWay}" ><dxmvvm:Interaction.Behaviors><dxmvvm:KeyToCommand Command="{Binding EditCommand}" EventName="MouseDoubleClick" CommandParameter="{Binding ElementName=gridControl, Path=SelectedItem}"/></dxmvvm:Interaction.Behaviors><dxg:GridColumn FieldName="BookName" Binding="{Binding BookName, Mode=TwoWay}" /><dxg:GridColumn FieldName="Symbol"  Binding="{Binding Symbol, Mode=TwoWay}"/><dxg:GridColumn FieldName="SymbolName" Binding="{Binding Symbol, Mode=TwoWay}"/><dxg:GridColumn FieldName="SpotPrice" Binding="{Binding SpotPri, Mode=TwoWay}"/><dxg:GridColumn FieldName="PriceFrom"  Binding="{Binding PriceFrom, Mode=TwoWay}"/><dxg:GridColumn FieldName="PriceTo"  Binding="{Binding PriceTo, Mode=TwoWay}"/><dxg:GridColumn FieldName="PriceChage"  Binding="{Binding IsUsePriceChage, Mode=TwoWay}"><dxg:GridColumn.EditSettings><dxe:CheckEditSettings Content="Price Chage" HorizontalContentAlignment="Right"  /></dxg:GridColumn.EditSettings></dxg:GridColumn></dxg:GridColumn><dxg:GridControl.View><dxg:CardView AllowEditing="True" ShowGroupedColumns="True" NavigationStyle="Cell" FixedSize="250" MinFixedSize="150" Name="view"CardHeaderBinding="{Binding Path=Data.Name, RelativeSource={RelativeSource Self}}" PrintAutoCardWidth="True" PrintMaximumCardColumns="2" /></dxg:GridControl.View></dxg:GridControl><DataGrid HorizontalAlignment="Left" Margin="335,120,0,0" VerticalAlignment="Top"/></Grid>

  刚开始的时候尝试Content="{Binding ElementName=gridControl,Path=SelectedItem.Symbol}"

 但是没有效果，原因未知，于是又尝试如下方法：

Content="{Binding Symbol}" DataContext="{Binding ElementName=gridControl,Path=SelectedItem}"

部分代码如下图：

 <dxc:ChartControl Name="chartControl1" AnimationMode="OnLoad" Grid.Row="1"><dxc:ChartControl.Titles><dxc:TitleContent="{Binding Symbol}" DataContext="{Binding ElementName=gridControl,Path=SelectedItem}"HorizontalAlignment="Center"><dxc:Title.ContentTemplate><DataTemplate><StackPanel  Orientation="Horizontal"><TextBlock Text="{Binding}" /></StackPanel></DataTemplate></dxc:Title.ContentTemplate></dxc:Title><dxc:Title Dock="Bottom" HorizontalAlignment="Right" FontSize="12" Foreground="Silver" Margin="0,10,0,0">From www.bea.gov</dxc:Title></dxc:ChartControl.Titles><dxc:ChartControl.CrosshairOptions><dxc:CrosshairOptions CrosshairLabelMode="ShowForNearestSeries"/></dxc:ChartControl.CrosshairOptions></dxc:ChartControl>

 效果如下图：
