//Add this Code on the Page Load
txtboxFirstName.Attributes.Add ("onKeyPress", "javascript:onCC_Changed();")

//Then IT Calls the function Name onCC_Changed() on the javascript here u can Add ur Code for GridView Calculation.

var GridView = document.getElementById(gridid);
var inputList = GridView.getElementsByTagName("input");
for (var i = 0; i < inputList.length; i++) {

//GridView.rows[i].cells[1].innerHTML

if (inputList[i].type == "checkbox") {
if (inputList[i].checked) {

//here u can Add ur changes

}
}
}
