In my project I have only RadDate Picker controls  which is dynamic based on the database values, and a button control.   

So I call the method for calculating CW in selected Index changed event of raddate picker, can this be done in client side? 

Now the problem is, my page is full of Date picker control, on each and every date selection the page is getting posted back to the server. So how can i overcome this problem of postback since every control is dynamic. Any help would be great.

Hello Kothai,

I suppose you mean Current Week with CW? In that case, you can use the following approach:
<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
    <Calendar runat="server">
        <ClientEvents OnDateSelected="dateSelected" />
function dateSelected(sender, args) {
    var cell = $(args.get_renderDay().DomElement);
    var parentRow = $(cell.parents()[0]);
    var weekCell = $(parentRow.children()[0]);
    var currentWeek = parseInt(weekCell.text());

In addition, please note that the displayed week number in the calendar strongly depends on your Culture configurations since there are different rules for week specifications when using different Cultures:

To apply your preferred week rule, you could choose one of the following options:
Copy Code
protected void Page_Load(object sender, EventArgs e)
    RadCalendar1.DateTimeFormat.CalendarWeekRule = System.Globalization.CalendarWeekRule.FirstDay;
    RadCalendar1.DateTimeFormat.CalendarWeekRule = System.Globalization.CalendarWeekRule.FirstFourDayWeek;
    RadCalendar1.DateTimeFormat.CalendarWeekRule = System.Globalization.CalendarWeekRule.FirstFullWeek;

Hope this helps. Please give the suggested solution a try and let me know if it works for you.
