</td>
</tr>
</table>
</fieldset>
</div>
</div>
</form>
</body>
</html>

then Aspx.cs design

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class Calendar : System.Web.UI.Page
{
public string controlToEdit;
public string isPostBack;

public Calendar()
{
LoadComplete += new EventHandler(Page_LoadComplete);
}
void Page_Load(object sender, EventArgs e)
{

if (!Page.IsPostBack)
{
controlToEdit = Request.QueryString["controlID"];
Session.Add("controlToEdit", controlToEdit);
isPostBack = Request.QueryString["isPostBack"];
Session.Add("isPostBack", isPostBack);

// Cast first day of the week from web.config file. Set it to the calendar
//Cal.FirstDayOfWeek = (System.Web.UI.WebControls.FirstDayOfWeek)Convert.ToInt32(ConfigurationManager.AppSettings["FirstDayOfWeek"]);

// Select the Correct date for Calendar from query string
// If fails, pick the current date on Calendar
try
{
Cal.SelectedDate = Cal.VisibleDate = Convert.ToDateTime(lblDate.Text);
}
catch
{
Cal.SelectedDate = Cal.VisibleDate = DateTime.Today;
}
// Fills in correct values for the dropdown menus
FillCalendarChoices();
SelectCorrectValues();
}
else
{
if (Session["controlToEdit"] != null)
controlToEdit = (string)Session["controlToEdit"];
if (Session["isPostBack"] != null)
isPostBack = (string)Session["isPostBack"];
}
}
void Page_LoadComplete(object sender, System.EventArgs e)
{
OKButton.OnClientClick = "javascript:window.opener.SetControlValue('" + this.controlToEdit + "','" + lblDate.Text + "','" + this.isPostBack + "');";
}

protected void FillCalendarChoices()
{
DateTime thisdate = (DateTime.Now).AddYears(5);

// Fills in month values
for (int x = 0; x < 12; x++)
{
// Loops through 12 months of the year and fills in each month value
ListItem li = new ListItem(thisdate.ToString("MMMM"), thisdate.Month.ToString());
MonthSelect.Items.Add(li);
//to add next next month name to the monthselect drop downlist control like aug then sept and so on....
thisdate = thisdate.AddMonths(1);
}

// Fills in year values and change y value to other years if necessary
for (int y = 2000; y <= thisdate.Year; y++)
{
YearSelect.Items.Add(y.ToString());
}

}

protected void SelectCorrectValues()
{
lblDate.Text = Cal.SelectedDate.ToShortDateString();
datechosen.Value = lblDate.Text;
MonthSelect.SelectedIndex = MonthSelect.Items.IndexOf(MonthSelect.Items.FindByValue(Cal.SelectedDate.Month.ToString()));
YearSelect.SelectedIndex = YearSelect.Items.IndexOf(YearSelect.Items.FindByValue(Cal.SelectedDate.Year.ToString()));
}

protected void Cal_SelectionChanged(object sender, System.EventArgs e)
{
Cal.VisibleDate = Cal.SelectedDate;
SelectCorrectValues();
}

protected void MonthSelect_SelectedIndexChanged(object sender, System.EventArgs e)
{
Cal.SelectedDate = Cal.VisibleDate
= new DateTime(Convert.ToInt32(YearSelect.SelectedItem.Value),
Convert.ToInt32(MonthSelect.SelectedItem.Value), 1); ;
SelectCorrectValues();
}

protected void YearSelect_SelectedIndexChanged(object sender, System.EventArgs e)
{
Cal.SelectedDate = Cal.VisibleDate
= new DateTime(Convert.ToInt32(YearSelect.SelectedItem.Value),
Convert.ToInt32(MonthSelect.SelectedItem.Value), 1); ;
SelectCorrectValues();

}

}

and call and other page
