Hi,:) you can do that using javascript . call one common function on each and every checkbox checked and set one flag value in hidden field and check this flag when you submit. function CallMe(id) { if(document.getElementByID(id).chekced==true) { //set hidden field value to true } else { //set hidden field value to false } } :-D -- modified at 7:33 Wednesday 21st November, 2007
