function Summary() {

var grid = eo_GetObject("Grid1");
var colCount = grid.getColumnCount();
var rowCount = grid.getItemCount();

var sum = 0;
for (i = 1; i < colCount - 1; i++) {
for (RI = 0; RI < rowCount - 1; RI++) {
var a = parseFloat(grid.getItem(RI).getCell(i).getValue());
sum = sum + a;

}

var total = parseFloat(grid.getItem(rowCount - 1).getCell(i).getValue());
var columnName = grid.getColumn(i).getHeaderText();

if (sum - total>1) {


var c = sum - total;

alert('Difference of this ' + columnName + ' is ' + c);
return false;
}

sum = 0;

}

I need to call this function to every cell edit .
C# I am generating dynamically column for gridview
for (int i = 0; i < dt2.Columns.Count; i++)
{
string columnName = dt2.Columns[i].ToString();
TextBoxColumn obj1 = new TextBoxColumn();
obj1.Name = columnName;
obj1.HeaderText = columnName;
obj1.DataField = columnName;
Grid1.Columns.Add(obj1);
}
