Something is wrong with your DatePopupControl, because your code worked fine for my own test control. Can you provide DatePopupControl source code?

Alright, let me try to guess. My first theory is: there is nothing to show in this popup. For example, if you add a userControl, which has only Grid tag inside without anything, you will see in the editor in Visual Studio, but it won't be visible as a popup child. But if you add a single textblock, it will be.
