Well, it looks like you are only using 3rd row to calculate every time!
Look here: "ctl00_ContentPlaceHolder1_GridView1_ctl03_txtqty"

Try:

JavaScript

function getMult()
{
   for(var i=0;i<ctl00_ContentPlaceHolder1_GridView1.rows.length;i++)
   {
     var a=parseFloat(document.getElementById("ctl00_ContentPlaceHolder1_GridView1_ctl0"+i+"_txtqty").value);
     var b=parseFloat(document.getElementById("ctl00_ContentPlaceHolder1_GridView1_ctl0"+i+"_txtrate").value);
     var c=parseFloat(document.getElementById("ctl00_ContentPlaceHolder1_GridView1_ctl0"+i+"_txtamt").value);
     var total=a*b;parseFloat(document.getElementById("ctl00_Content;).valuetPlaceHolder1_GridView1_ctl0"+i+"_txtamt").value=total.toFixed(2));
   }
}

Hi Amit,

Please use the following Javascript function to get result.

C#

var grid = document.getElementById('<%=GridView1.ClientID %>');
      for (var r = 0; r < grid.rows.length; r++) {
          var row = grid.rows[r].getElementsByTagName('input');
          row[2].value = (row[0].value * row[1].value);
      }

Please do let me know, if you have any doubt.
