Disable Future and Past Date Of AJAX Calendar in ASP.Net C#.net

Now let us create the one sample application to do our task as:

1. "Start" - "All Programs" - "Microsoft Visual Studio 2010".
"File" - "New web Site" - "C#" - "Empty Website" (to avoid adding a master page).
Provide the web site a name such as Ajax Calendar or another as you wish and specify the location.
Then right-click on Solution Explorer - "Add New Item" - "Default.aspx" page.
Drag and drop one textbox and one Script Manager from Ajax Extension section on the <form> section of the Default.aspx page.

Now the source code of the Default.aspx should look as in the following:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DissableDates.aspx.cs" Inherits="DissableDates" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<h3>

</h3>

<br />

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<asp:CalendarExtender ID="Calendar1" runat="server" TargetControlID="TextBox1" Format="dd/MM/yyyy">

</asp:CalendarExtender>

</center>

</div>

</form>

</body>

</html>

Now use the following code in the .cs file.

using System;

public partial class DissableDates : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

Calendar1.StartDate = DateTime.Now;

}
