datetime picker

i am using datetime picker in my form .
but while select a date it is showing date in "mm/dd/yyyy" format .
But i want date to be displayed in "dd/mm/YYYY" format .
its very urgent

in the designer form,
1 - select your datetimecontrol.
2 - In the appearence section, change the format property to 'custom'
3 - in the behavior sectionm set the customFormat property to the format you like

The Format property of the DateTimePicker can be set to Long (default), Short, Time or Custom. The actual format of the first three is dictated by the system's Regional Settings, so the same date will display differently on two different systems with different regional settings. The idea is that every user sees dates, times and numbers in the format that they expect. Those in the US will see dates in M/dd/yyyy format while those of us here in Australia will see dates in d/MM/yyyy format. It's generally better to use system formats so each user gets what they expect.

If you want to force a specific format regardless of regional settings, you set the Format to Custom and then set the CustomFormat to whatever you want. In your case you'd set the CustomFormat to d/MM/yyyy, or dd/MM/yyyy if you wanted to force a leading zero on single digit days. Note that the M's must be upper case and the rest lower case. Lower case m is for minutes.
