WPF中在使用DateGrid时，根据绑定数据源来显示与隐藏整列

XAML代码：

　　　　　　　　　 <FrameworkElement x:Name="dummyElement" Visibility="Collapsed"/>
                <DataGrid Grid.Column="0" x:Name="DgData" SelectionMode="Extended" Margin="5" BorderBrush="#BBB" BorderThickness="1"
                  Style="{StaticResource DefaultDataGrid}"
                  ItemsSource="{Binding OcPlanFlowSourceCanEdit }"
                  SelectedItem="{Binding SelectedEntityMaterial, Mode=TwoWay}" >
                    <DataGrid.Columns>
                        ...
                        ...
                        <DataGridTextColumn Header="投料数量" Width="100" Binding="{Binding Path=Qty,StringFormat=0.00}" ElementStyle="{StaticResource contentRightStyle}" Visibility="{Binding DataContext.RedCanNotChange, Source={x:Reference dummyElement},Converter={StaticResource BoolToVisibleConverter}}"/>
                        ...
                        ...
                    </DataGrid.Columns>
                </DataGrid>
