Holiday Calender List in ASP.Net C# - DotNet Brother

Well so most of the time as a developer we get requirement to develop a calender with holidays list, so here i have tried to explain this in very simple way. Just follow step by step to develop this. 

Open Microsoft Visual Studio --> Click File --> New --> Website --> Enter file Name --> OK 

Lets write few code on page Default.aspx page 

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <form id="form1" runat="server">
        <asp:Calendar ID="Calendar1" runat="server" Height="444px" Width="100%"OnDayRender="Calendar1_DayRender"
            DayNameFormat="Full" ForeColor="#000099" NextMonthText="">
            <DayHeaderStyle BackColor="#666699" ForeColor="Maroon" />
            <DayStyle BackColor="#CCCCCC" Font-Bold="True" Font-Italic="False" ForeColor="#000066" />
            <SelectedDayStyle BackColor="#9999FF" Font-Bold="True" ForeColor="Maroon" />
            <WeekendDayStyle BackColor="#999966" Font-Bold="True" ForeColor="#990000" />
        <asp:Label ID="LabelAction" runat="server"></asp:Label>

Now write the below code in .cs page.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections;
public partial class _Default : System.Web.UI.Page
    Hashtable HolidayList;
    protected void Page_Load(object sender, EventArgs e)
        HolidayList = Getholiday();
        Calendar1.Caption = "Calender";
        Calendar1.FirstDayOfWeek = FirstDayOfWeek.Monday;

        Calendar1.DayStyle.HorizontalAlign = HorizontalAlign.Center;
        Calendar1.DayStyle.VerticalAlign = VerticalAlign.Middle;

        //Calendar1.OtherMonthDayStyle.BackColor = System.Drawing.Color.AliceBlue;
    private Hashtable Getholiday()
        Hashtable holiday = new Hashtable();
        holiday["1/1/2013"] = "New Year";

        holiday["9/2/2013"] = "Onam";
        holiday["9/5/2013"] = "Teachers Day";
        holiday["9/21/2013"] = "Ramzan";
        holiday["9/27/2013"] = "Ayutha Pooja";
        holiday["9/28/2013"] = "Vijaya Dasami (Dusherra)";

        holiday["11/28/2013"] = "Bakrid";
        holiday["12/25/2013"] = "Christmas";
        holiday["12/28/2013"] = "Muharram";
        return holiday;
    protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
        if (HolidayList[e.Day.Date.ToShortDateString()] != null)
            Literal literal1 = new Literal();
            literal1.Text = "<br/>";
            Label label1 = new Label();
            label1.Text = (string)HolidayList[e.Day.Date.ToShortDateString()];
            label1.Font.Size = new FontUnit(FontSize.Small);
    protected void Calendar1_VisibleMonthChanged(object sender, MonthChangedEventArgs e)
        LabelAction.Text = "Month changed to :" + e.NewDate.ToShortDateString();
    protected void Calendar1_SelectionChanged(object sender, EventArgs e)
        LabelAction.Text = "Date changed to :" + Calendar1.SelectedDate.ToShortDateString();
