first thing are you trying to access previous page control, secand are you sure you are checking a right check box because ur event name and control name is missmatch ie "CheckBox1" v/s chktest. pls clear with information to identitify issue.

If this is all the processing that happens on the check changed, you could do it on the client side. By setting display to none.
