This isn't exactly what you asked for, but it's as close as I can get'cha :)

Can use client functional of CalendarExtender to send info to postback, and do something from there. See Snippet...
***ASPX PAGE****
 

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
 

<!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 runat="server">

    <title>Cal Extender Event</title>

    <script type="text/javascript">

		

		function selectionChanged(sender,args)

		{

			//just about all calendar properties, etc are avail by using

			//sender._[propertyName]

			//If you wanted to send back a more complex argument then I have used

			//Sys.Serialization.JavaScriptSerializer to package them up

			//then de-serialize on the server side :)

			__doPostBack(sender._id,sender._selectedDate);

			

		}

    </script>

</head>

<body>

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

		<asp:ScriptManager ID="sm" runat="server" />

		

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

		<asp:Button ID="btnCal" runat="server" Text="Show Calendar" />
 

		<cc1:CalendarExtender 

			ID="CalendarExtender1" 

			runat="server"

			TargetControlID="txtCal" 

			PopupButtonID="btnCal"

			OnClientDateSelectionChanged="selectionChanged" />
 

    </form>

</body>

</html>
 
 

****CODE BEHIND****
 

public partial class Default7 : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

        if (IsPostBack)

        {

            string eTarget = Request.Params.Get("__EVENTTARGET");

            string eArg = Request.Params.Get("__EVENTARGUMENT");
 

            if (!string.IsNullOrEmpty(eTarget) && !string.IsNullOrEmpty(eArg))

            {

                doStuff(eTarget, eArg);

            }

        }
 

    }
 
 

    private void doStuff(string cTarget, string cArg)

    {

        //do something

    }

}
