Hello Chandrasekaran,

A possible approach is shown below:

    
            <script language="javascript" type="text/javascript"> 
        
                function CalculateAge(sender, args) 
        
                { 
        
                    var current = new Date(); 
        
                    var day = 1000 * 60 * 60 * 24 
        
                    var age = current - args.get_newDate(); 
        
                    alert("You are " + Math.round(age / day / 365.25) + " years old"); 
        
                } 
        
            </script> 
        
            <div> 
        
                <telerik:RadDatePicker ID="RadDatePicker1" runat="server"> 
        
                    <ClientEvents OnDateSelected="CalculateAge" /> 
        
                </telerik:RadDatePicker> 
        
            </div>

Hi,
i am also using firefox3.05 only..this is my function

function AgeCalculate(sender, args)

{

var current = new Date();

var txtDOB = document.getElementById('<%=txtDOB.ClientID %>');

var byear = txtDOB.value.substring(0, 4)

var CurrentDate = new Date();

var age = parseInt(CurrentDate.getFullYear()) - parseInt(byear)

var lblAgeCalculation = document.getElementById('<%=lblAgeCalculation.ClientID %>');

lblAgeCalculation.innerText = "Age " + age + " year(s)";
