Is it possible to use DateTimePicker (Winforms) to pick both date and time (in the dropdown)? How do you change the custom display of the picked value? Also, is it possible to enable the user to type the date/time manually?

Set the Format to Custom and then specify the format:
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM/dd/yyyy hh:mm:ss";
or however you want to lay it out. You could then type in directly the date/time. If you use MMM, you'll need to use the numeric value for the month for entry, unless you write some code yourself for that (e.g., 5 results in May)
Don't know about the picker for date and time together. Sounds like a custom control to me.
Unfortunately, this is one of the many misnomers in the framework, or at best a violation of SRP.
To use the DateTimePicker for times, set the Format property to either Time or Custom (Use Custom if you want to control the format of the time using the CustomFormat property). Then set the ShowUpDown property to true.
Although a user may set the date and time together manually, they cannot use the GUI to set both.
You can get it to display time. From that you will probably have to have two controls (one date, one time) the accomplish what you want.
I'm afraid the DateTimePicker control doesn't have the ability to do those things. It's a pretty basic (and frustrating!) control. Your best option may be to find a third-party control that does what you want.
For the option of typing the date and time manually, you could build a custom component with a TextBox/DateTimePicker combination to accomplish this, and it might work reasonably well, if third-party controls are not an option.
If you need (24 hours) military time. You should use "HH" instead of "hh".
"MM/dd/yyyy HH:mm"
