Here is my statement: a set of check boxes requiring validation is a sign of wrong UI design, its logic.
I must add: not always.
If you can clearly explain your ultimate goal, probably I would be able to explain why and what else could be done.

Please see my comment to the question.

For now, when I still don't know your goal, try to ask yourself one question: shouldn't the check boxes representing countries be radio buttons?

Explain your purpose from the application standpoint, only then we can discuss it.

i need for a tourism management..
the user have to check what are all the places they have visited.. for that only i need..
for ex: i the user visited tajmahal in india then in UI we provide
<checkbox>Country name [say India]
<checkbox>State name [say Delhi]
<checkbox>City name [say Agra]
<checkbox>Tourist place [say Tajmahal]
here if the user visited Tajmahal then he must select All the checkbox. i.e he is able to check 4 times.
But what i need is if the user selects Tajmahal then his parent classes also should be selected automatically. now the times saves here coz the user selects all the checkboxes using single click.
got my point??

Thank you for clarification. It makes it even more apparent that the design is wrong.
The idea is: if India is not checked, all of the Indian details should be hidden, if some Indian state is not checked, all the detail related to this state should be hidden, and so on.
As soon as you feel a need in validation, consider UI design is wrong.

Your criteria for UI design should include this: no validation. At the same time, say, text box content usually should be validated, excluding the cases when any text can be considered as valid. You can also filter out some characters.

okay i got u..
now i'm not need to validate just simply need to reduce the no.of clicks.

Sergey Alexandrovich Kryukov 22-Apr-14 22:38pm

Very good. Hiding (or, actually, disabling) some subsets of control, you will avoid both validation and extra clicks.
Will you accept the answer formally (green "Accept" button)?
