Using DataTrigger to apply different Views to the same ViewModel

Question

I have a ViewModel where I created a bool DisplaySummary property. When this is true, a SummaryView is to be use to render that ViewModel, otherwise a DatailedView is to be used.

I am in doubt about how I should proceed from here:

<DataTemplate DataType="{x:Type vm:AwesomeViewModel}">
    <ContentControl Content="{Binding}">
        <ContentControl.Style>
            <Style>
                 #### WHAT I SHOULD PUT HERE?
            </Style>
        </ContentControl.Style>
    </ContentControl>
</DataTemplate>

<DataTemplate x:Key="SummaryTemplate">
    <vw:SummaryViewScreen />
</DataTemplate>

<DataTemplate x:Key="DetailedTemplate">
    <vw:DetailedViewScreen />
</DataTemplate>

EDIT: at first I tried to use DataTemplateSelector, but since it does not respond to PropertyChanged, I had to use DataTriggers.

Use DataTrigger to switch ContentTemplate:

<DataTemplate DataType="{x:Type vm:AwesomeViewModel}">
  <ContentControl Content="{Binding}">
    <ContentControl.Style>
      <Style TargetType="ContentControl">
        <Setter Property="ContentTemplate"
                Value="{StaticResource DetailedTemplate}"/>
           <Style.Triggers>
             <DataTrigger Binding="{Binding DisplaySummary}" Value="True">
                <Setter Property="ContentTemplate"
                        Value="{StaticResource SummaryTemplate}"/>
              </DataTrigger>
            </Style.Triggers>
       </Style>
     </ContentControl.Style>
   </ContentControl>
 </DataTemplate>
