Loop minimization problem.

Question

I want to sort my searching process, currently i need to check everyone checkbox, I want to know that m is there a sort way by which we can minimize our checking  process, Is there a control like groupbox by which we can take all these checkbox under the group, and check if group item is edited or not, if edited then we take a loop on it, if not edited then no need of loop,
Please if you have an idea, then tell me.
