Jquery Date Picker arrow key should be prevented

Jquery Date Picker arrow key should be prevented

I want to force the user to only use the drop down and calendar to
select a date in the DatetimePicker control.

I do NOT want them to select the control, then use the up and down
arrow keys to change the date.

How can I prevent them using the arrow keys?

Any help much appreciated.
