WPF扩展工具包：自定义datetimepicker时间格式

Question

How do I milliseconds to my string format. Here's what I have:

<wpfTool:DateTimePicker
                        x:Name="DTP_To_TAtab" 
                        Format="Custom" 
                        FormatString="M/d/yyyy HH:mm:ss"
                        TimeFormat="Custom"
                        TimeFormatString="HH:mm:ss"

I want the time to look like this:

14:15:16.123
