New Post: TimePicker: Increase the height of the dropdown list

Anyone know how to style TimePicker so that you can increase the size of the dropdown to display more items. I tried

<xctk:TimePicker x:Name="ClockInTime" Value="9:00 AM" VerticalAlignment="Top" Margin="10" Height="40" FontSize="18" TimeInterval="0:30:0" ClipToBounds="True">

<xctk:TimePicker.Resources> 
                            <Style TargetType="Popup">
                                <Setter Property="Height" Value="500" />
                            </Style>
                        </xctk:TimePicker.Resources>

</xctk:TimePicker>

But it only created a larger dropdown with 4 items displaying in the center of the dropdown.
