Objective: Set Ajax CalendarExtender startdate to the clients current date

On the start of the application or content page

Need the client date to be the start date of the calendar

I’ve seen how the selected date can be set via Javascript

It is using the sender._selectedDate to be set the client date

Is there a sender._startDate that can be on the loading of the page?

Ex:Set the selected date on the OnClientDateSelectionChanged

    function checkDate(sender, args) {

        if (sender._selectedDate < new Date()) {

                alert("You cannot select a day earlier than today!");

                sender._selectedDate = new Date();

                sender._textbox.set_Value(sender._selectedDate.format(sender._format))

         }

     }

<asp:CalendarExtender ID="CalendarExtender1"

                 runat="server"

                 TargetControlID="txtStartDate"

                 PopupButtonID="ImageButton1"                                           

                 OnClientDateSelectionChanged="checkDate"  >

</asp:CalendarExtender

Something like

    function checkDate(sender, args) {

        if (sender._StartDate < new Date()) {

                alert("You cannot select a day earlier than today!");

                sender._STartDate = new Date();

                  }

     }

<asp:CalendarExtender ID="CalendarExtender1"

                 runat="server"

                 TargetControlID="txtStartDate"

                 PopupButtonID="ImageButton1"                                           

                 OnClientShowing="checkDate"  >

</asp:CalendarExtender
