Is there any way to allow user to select 1 checkbox only? Or maybe if the user selects more than 1 checkbox, an alertbox will alert him that he has selected more than 1 checkbox.

why not just use radio buttons? that's the job of radios.

Coz i'm required to use only checkboxes... Hmm.. does that means there's no way to stop the user from selecting multiple checkboxes....

this sounds like an Act of Management, which is similar to an Act of God, except that the former makes less sense, and is more random.

Hmm.. seems like the requirment is to enforce a single selection from a group of choices.

This requirment is directly and fully suppored by radio buttons - without any additional coding!!

Using checkboxes as radio buttons has to bads:
one: You have to write, test, implement, and maintain more code. This is unnecessarily. From a professional software development perspective it's unacceptable.

two: This goes against generally accepted and well understood interface design. Users naturally understand that when they see a group of checkboxes that they can make multiple choices.

If you were a carpenter and I were a lady, would you let me tell you how to build a house? Would you love me anyway?

Who's requiring you to do so? This guy?
