title: How to stop WebForm_doPostBack() conditionally?
body: <p>I need to run some script by onclick() of some , checkbox particularly, to decide should i invoke WebForm_doPostBack() or not. </p>
  
  <p>If I will submit form in myScript() myself, it will not cause validation of another asp.net validators, so I really need a native WebForm_doPostBack() call.</p>
  
  <p>Should I handle a submit form event or are there any more "asp.net" ways to do it?</p>
  
  <p>CustomValidators don't work with checkboxes:).</p>
