Как получить последний элемент из Listview, когда элементы выделены множественным выбором

У меня небольшая проблема с множественным выбором и свойством SelectedItem. Мое приложение работает следующим образом: когда я нажимаю на запись в Listview, данные из этой записи отображаются в текстовых полях. И вот моя проблема. Я хочу добиться такой функциональности: когда я нажимаю одну за другой записи, я хочу отобразить данные последнего выбранного элемента. К сожалению, SelectedItem работает только для первого элемента. Не могли бы вы помочь мне? Я приложил необходимую часть кода:

MainWindow.xaml

<ListView Name = "EmployeeListView" HorizontalAlignment = "Left" Height = "160" Margin = "0,153,0,0" VerticalAlignment = "Top" Width = "755" Grid.Row = "1" ItemsSource = "{Binding FilteredCollection, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedItem = "{Binding SelectedEmployee, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedIndex = "{Binding SelectedIndex}" IsSynchronizedWithCurrentItem = "True">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header = "EmployeeName" Width = "150" DisplayMemberBinding = "{Binding EmployeeName}" />
                    <GridViewColumn Header = "EmployeeID" Width = "150" DisplayMemberBinding = "{Binding EmployeeID}" />
                    <GridViewColumn Header = "EmployeeSalary" Width = "150" DisplayMemberBinding = "{Binding EmployeeSalary}" />
                    <GridViewColumn Header = "EmployeeDesigner" Width = "150" DisplayMemberBinding = "{Binding EmployeeDesigner}" />
                    <GridViewColumn Header = "EmployeeEmailID" Width = "150" DisplayMemberBinding = "{Binding EmployeeEmailID}" />
                </GridView>
            </ListView.View>
            <ListView.ItemContainerStyle>
                <Style TargetType = "{x:Type ListViewItem}">
                    <Setter Property = "IsSelected" Value = "{Binding Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView>

Employee.cs
