        <DataTemplate DataType="{x:Type my:Section}">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Path=Name}"/>
                <TextBlock Text="  "/>
                <TextBlock Text="{Binding Path=Instructor}"/>
                <TextBlock Text="  "/>
                <TextBlock Text="{Binding Path=Cours}"/>
            </StackPanel>
        </DataTemplate>

        <DataTemplate DataType="{x:Type my:Instructor}" x:Key="InstructorDataTemp">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Path=FirstName}"/>
                <TextBlock Text=" "/>
                <TextBlock Text="{Binding Path=LastName}"/>
            </StackPanel>
        </DataTemplate>

        <DataTemplate DataType="{x:Type my:Cours}" x:Key="CourseDataTemp">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Path=Name}"/>
            </StackPanel>
        </DataTemplate>

I am using the section template right now. The section template correctly displays the Section's Name, but the Instructor and Cours both show up as basic toStrings. I would like them to show up as defined in the other data templates. Any help is appreciated

Thanks

I solved it by using an IValueConverter for the instructor (in the section) and in the binding for the cours (in the section) just saying Cours.Name
