Question

I have Two Labels such as FixedTotal and TotalPercent, One GridView which has One Row such as

    ReferenceID       Percentage          Amount
   --------------    -------------       --------
        1                5                 1000

Here I want to change the “Percentage” Column value 5 with the TotalPercent label’s text.
and I want to display the “Amount” Column value 1000 in the FixedTotal label.
I also want to check whether the Grid has row or not? How to do this?
The Columns are BoundField Columns..

Getting/Setting value to gridview cells, you need to know the Row Index of Gridview, you can pass row index when you call JS function from gridview

<script language="javascript" type="text/javascript">
function update(rowIndexOfGridview) {
    var ri = rowIndexOfGridview; 
    var grd = document.getElementById('<%= GridView1.ClientID %>');

    CellValue = grd.rows[ri].cells[1].childNodes[0].value; // get
    grd.rows[ri].cells[2].childNodes[0].value = CellValue; assign
    ...........
    .............
}
