Display year and select year in calendarextender - ajax

display year and select year with a minimum clicks(normally it requires three click of year, month and finally day). Can someone help me to achieve this using ajax calendarextender…

currently I can display year using this code segment :
<asp:TextBox ID=“TextBox1” runat=“server”></asp:TextBox>
<cc1:CalendarExtender ID=“CalendarExtender1”
runat=“server” TargetControlID=“TextBox1” OnClientShown=“ChangeCalendarView” />
Then add this to the <head> section
<head runat=“server”>

<script type=“text/javascript”>
function ChangeCalendarView(sender,args)
sender._switchMode(“years”, true);

Im problem with select year in one click instead of three mouse clicks.
pls help, thanks
