Using what technology? JavaScript? server-side code?

Hi
This is how you can use Javascript to solve the problem.

XML

<asp:TextBox ID="txtHoursorAmount" runat="server"  onblur="transferValue()"/>
            <input type="hidden" name="hdnAmountorHours" id="hdnAmountorHours" runat="server" />

script is

XML

<script type="text/javascript">
        function transferValue()
        {
            var inputVal = document.getElementById("txtHoursorAmount").value;
            document.getElementById("hdnAmountorHours").value=inputVal;
            alert(inputVal);
        }
    </script>

Good Luck
