ASP.NET AJAX Calendar Extender – Tips and Tricks

The code you want is stated in that article as follows:

C#

<head runat="server">
    <title>Calendar Extender</title>
    <script type="text/javascript">
    function checkDate(sender,args)
{
 if (sender._selectedDate > new Date())
            {
                alert("You cannot select a day earlier than today!");
                sender._selectedDate = new Date(); 
                // set the date back to the current date
sender._textbox.set_Value(sender._selectedDate.format(sender._format))
            }
}
    </script>
</head>
Call the code:
   <form id="form1" runat="server">
        <asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown" />
        <div>
          
            <asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown"></asp:textbox>
            <cc1:calendarextender id="CalendarExtender1" xmlns:cc1="#unknown">
            runat="server" OnClientDateSelectionChanged="checkDate" TargetControlID="TextBox1" />
 
        </cc1:calendarextender></div>
    </form>
