Date Time Picker doesn't show Date & Time

[FastEddie]

I have a datetimepicker control where I want to show both the date and time but so far have not been able to do so.

I have the properties format set to custom and then through code I am trying to do this:

' Format DateTime
        dtpShow.Value = CDate(dtShowDateTime.ToString("u"))
        dtpStart.Value = CDate(dtStartDateTime.ToString("u"))
        dtpEnd.Value = CDate(dtStopDateTime.ToString("u"))

At run time the control is only showing Long or Short depending on the properties. I want to show it like this: 2007-9-18 00:00:00
