I'm looking for a simple time picker control for WPF. I've found found this one: http://marlongrech.wordpress.com/2007/11/18/time-picker/ but it has some issues e.g. you can't type in "00" into it, the second zero won't appear.

However, I don't want to just display the data as it is but slightly modified, e.g. I might want to display all the zipcodes to display with a "-0000" on the end, or I may want to display "n/a" if a cell is blank.

On this project, though, I'm finding PreviewMouseMove is not firing when...

I see comments saying that Custom Type Descriptors will work too, but no...
