title: How do I get checked boxes values from the placeholders?
body: <p>I'm creating checkbox to placeholder. Its about to bus tickets. If bus has 50 seats, I create 50 checkboxes. Thats ok, but How I can get which checkbox is checked? </p>
  
  <p>Can I put checked boxes an arraylist? I know dynamic controls removed after postback can I hold checked boxes id's with viewstate?</p>
