I'm using a MVVM-Pattern with a ModelView-First approach. This works fine, so far. Now I have a UserControl (View) which should display various content depending on a Property located in my ViewModel. First, I tried to solve the issue with DataTemplates and a DataTemplateSelector (<a href="http://www.switchonthecode.com/tutorials/wpf-tutorial-how-to-use-a-datatemplateselector" rel="nofollow">See this tutorial</a>) This was working very well. But I was not happy with the solution, because then I have a class (the overrided DataTemplateSelector) which is not connected to the ViewModel and can't be filled from the model. So I tried to create a own TemplateSelector which uses a Property from the ViewModel. Unfortunately the DataTrigger is not triggering. The Binding from a CheckBox to the ViewModel is also working but not at the DataTrigger (even the designer can't find this path). Ok, please have a look at the code: <pre><code><UserControl.Resources>  <DataTemplate x:Key="templateUser"> <Image Name="logo" Source="blanked out" HorizontalAlignment="Center" VerticalAlignment="Center" /> </DataTemplate>  <DataTemplate x:Key="templateAdmin"> <TextBlock Background="Yellow" Margin="3" Text="YEAH, I'm an Administrator" /> </DataTemplate>  <DataTemplate x:Key="myTemplateSelector"> <ContentControl x:Name="DynamicContent" ContentTemplate="{StaticResource templateUser}"/> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=IsAdministrator}" Value="true"> <Setter TargetName="DynamicContent" Property="ContentTemplate" Value="{StaticResource templateAdmin}" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </UserControl.Resources> <Grid> <ContentPresenter ContentTemplate="{StaticResource myTemplateSelector}"/> </Grid> </code></pre> Of course, I can seperate the Task in two further contentcontrols, but I don't want to maintain those if same content is intersecting. So can someone suggest anything? Best regards, and thanks in advance!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
