calendar control using dropdown in asp.net

Hi,

Here I'm providing link for generating calender with dropdownlist controls

http://www.codeproject.com/KB/scripting/JavaScriptCalendar.aspx

I hope this links helps you to understand calender control details


And I tried some code for generating months in dropdown list

<form id="form1" runat="server">
<div>
  <table>
    <tr>
      <td>Year :
          <asp:DropDownList ID="ddlyear" runat="server">

      </td>
      <td>Month :
          <asp:DropDownList ID="ddlmonth" runat="server" AutoPostBack="True"
              onselectedindexchanged="ddlmonth_SelectedIndexChanged">

      </td>
      <td>Date :
          <asp:DropDownList ID="ddldate" runat="server">

      </td>
    </tr>
  </table>
</div>
</form>

And the code behind file contains following code

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {

        for (int i = 1; i <= 12; i++)
        {
             System.Globalization .DateTimeFormatInfo nm=new System.Globalization.DateTimeFormatInfo ();
             ddlmonth.Items.Add (new ListItem (nm.GetMonthName(i).ToString (),i.ToString ()));

        }
        for (int i = 1900; i <= System.DateTime.Now.Year; i++)
        {


            ddlyear.Items.Add (new ListItem( i.ToString (),i.ToString ()));

        }

    }
}
protected void ddlmonth_SelectedIndexChanged(object sender, EventArgs e)
{
    ddldate.Items.Clear();
    for (int i = 1; i <= System.DateTime.DaysInMonth(int.Parse(ddlyear.SelectedValue), int.Parse(ddlmonth.SelectedValue)); i++)
    {
          ddldate .Items.Add (new ListItem (i.ToString (),i.ToString ()));
    }

}

In the above code I filled days based on month selected by user.

If you can use jquery it is easy fill dynamically with asynchronous requests.
or use Ajax update panels also

All the Best
