Some values are stored in the database.On the basis of some field 1 of the checkbox is to be selected in the checkbox group. Please tell me how can I have the checkbox checked when the form is loaded?

HI swarnap!!
on page load use javascript function to checked the checkbox
e.g

 document.formname.checkboxname.checked=true;
if checkbox is part of checkboxgroup then
 document.formname.checkboxname[0].checked=true;
where [0] is first checkbox

hope this will help you

Cheers :)
