Hi All,

I am new to .Net. I am converting a source which is in .net 1.1 to .net3.5.

In 1.1 those people had used scritps for calendar popup.

Let me show the sample code first

In JSCalendar.aspx


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

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

<head runat="server">

<LINK href="cal/popcalendar.css" type="text/css" rel="stylesheet">

<title>Test Calender</title>

<script language="javascript" src="cal/popcalendar.js"></script>

<script language="javascript">

function test()



var strValue = document.getElementById('txt_Date').value;


if (strValue != '')


var strarr = strValue.split("/");

strValue = strarr[1] + '/' + strarr[0] + '/' + strarr[2];

var d = new Date(strValue);

var d1= d.getDate();

d1 = d1 + 3;


var Month = d.getMonth();

Month = Month + 1;

strMonth = Month + "";

if(strMonth.length == 1)

Month = '0' + Month;

var strDay = d.getDate() + "";

if(strDay.length == 1)

strDay = '0' + strDay;

document.getElementById('txt_Date1').value = strDay + '/' + Month + '/' + d.getFullYear();






<form id="form1" method="post" runat="server">


<TABLE id="tbl_control" cellSpacing="0" cellPadding="0" border="0">


<TD align="right"><asp:label id="lbl_Date" Font-Bold="true" runat="server">Date :</asp:label></TD>

<TD align="center" style="width: 107px"><asp:textbox id="txt_Date" runat="server" Columns="6" Width="99px" OnTextChanged="txt_Date_TextChanged"></asp:textbox></TD>

<td></td><td style="width: 107px"></td>



<TD align="right"><asp:label id="lbl_Date1" Font-Bold="true" runat="server">Date 1 :</asp:label></TD>

<TD align="center" style="width: 107px"><asp:textbox id="txt_Date1" runat="server" Columns="6" Width="99px" OnTextChanged="txt_Date1_TextChanged"></asp:textbox></TD>

public string Text




return lbl_Date.Text;




lbl_Date.Text = value;



protected void txt_Date_TextChanged(object sender, EventArgs e)


//Iam tring to print the value




What I am going to do is:

1. calling js for calendar popup and selecting the date.

2. With the date selected I am printing it in the testbox.

3. After getting the date I am calling a function test() in js which will execute in aspx file and will take the value of selected date and will add 3 days more to it and it will print it in another textbox (txt_Date1).

upto now it is ok... I am getting what I am expected.

Now, the problem started for me... when a value or some data is changed in txt_Date... I am calling a method in aspx.cs file called txt_Date1_TextChanged. Here I want to access the values of txt_Date and txt_date1 and also I want to print the values of txt_Date and txt_date1.

Please help me...

Thanks in advance.......
