I am having the same problem myself and the only solution (well, workaround) I could find was this:

ASP.NET Ajax CalendarExtender will not update SelectedDate value

While this is helpful, linking to another SO question isn't an acceptable answer here. – Jun 24 '12 at 16:09

I hope this can help you, this worked for me.

String tmp_;
protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            if (Request[txtCalendarExtender.UniqueID] != null)
            {
                if (Request[txtCalendarExtender.UniqueID].Length > 0)
                {
                    this.tmp_ = Request[txtCalendarExtender.UniqueID];
                }
            }
        }
    }
