hi,

try the below code

Product 1 <input type="text" id="qty1" name="qty1" ><input type="text" id="Price1" name="Price1" value="7.50">
<input type="text" id="tot1" name="tot1">

Product 2 <input type="text" id="qty2" name="qty2" ><input type="text" id="Price2" name="Price2" value="10.50">
<input type="text" id="tot2" name="tot1">

<input type="button" onclick="calculate();" value="ok">

<script language="javascript">
function calculate()
{
document.getElementById("tot1").value = document.getElementById("qty1").value * document.getElementById("Price1").value;
document.getElementById("tot2").value = document.getElementById("qty2").value * document.getElementById("Price2").value;
}

You can do this like this.

function MultiplyTwoNumber()

{

var a=document.getElementById(<controlId>).value;

var b=document.getElementById(<controlId>).value;

var c = parseFloat(a) * parseFloat(b) ;

document.getElementById(<labelcontrolid>).value = c;

}

Call this from button control.

<asp:Button OnClientClick="return MultiplyTwoNumber();" Text="Multiply" runat="server" />
