Javascript confirm message from code behind

Question

Hi all,

Can anyone suggest me how to write the confirm box in code behind
and i want to get the return value whether the user clicked 'ok' or
'cancel',
Depending on that i need to process further using if else .
"I want pass one value  which is form databse to confirm message."
Thats y i am using this calling from code behind.


Thanks in advance,
Deepthi
