hi.. I've been playing around with radcalendar and noticed that when I click a date it sets the value of selected date to the date as expected. However if I then click the same date the value of radcalendar1.SelectedDate is set to 01/01/0001 00:00:00 .

If you click different days radcalendar.SelectedDate is always set to the correct value, it just seems to occur when you click the same date.

is there a simple fix for this?

<telerik:RadCalendar ID="RadCalendar1" Runat="server" CultureInfo="en-GB"
    MultiViewColumns="4" MultiViewRows="1"
        EnableMultiSelect="false" AutoPostBack="true"
    OnSelectionChanged="RadCalendar1_SelectionChanged" SelectedDate=""  
    ViewSelectorText="x" Skin="Windows7">
        <SpecialDays>
            <telerik:RadCalendarDay Date="" Repeatable="Today">
                <ItemStyle CssClass="rcToday" />
            </telerik:RadCalendarDay>
        </SpecialDays>

Hi Jake,

This is the default and expected behavior of RadCalendar since its SelectedDate cannot be assigned null, therefore it becomes the absolute possible minimal date. If you want to avoid the event when a day is deselected, please try to add the following condition:

That should do the trick.

ah then I guess I want to prevent deselect client side as per this article .. http://www.telerik.com/community/forums/aspnet-ajax/calendar/how-to-disable-date-deselect.aspx .. Thanks

<script type="text/javascript">
        var date = null;
        function OnDateSelecting(sender, args) {
            var currentDate = args.get_renderDay().get_date();
            var newDate = new Date(currentDate[0], currentDate[1], currentDate[2]);
            if (args.get_renderDay().IsSelected && isDatesEquals(date, newDate)) {
                args.set_cancel(true);
            }
        };

        function OnDateClick(sender, eventArgs) {
            var d = eventArgs.get_renderDay().get_date();
            date = new Date(d[0], d[1], d[2]);
        }

        function isDatesEquals(date1, date2) {
            if (date1.getFullYear() == date2.getFullYear() && date1.getMonth() == date2.getMonth() && date1.getDate() == date2.getDate()) {
                return true;
            }
            else return false;
        }
