Hi,

I'm integrating jquery fullcalendar into my application. Here is the code i'm using:

in index.aspx:

<script type="text/javascript">
   $(document).ready(function() {
       $('#calendar').fullCalendar({
           events: "/Scheduler/CalendarData"
       });
   });  
</script>

<div id="calendar">
</div>

Here is the code for Scheduler/CalendarData:

public ActionResult CalendarData()
    {

        IList<CalendarDTO> tasksList = new List<CalendarDTO>();

        tasksList.Add(new CalendarDTO
        {
            id = 1,
            title = "Google search",
            start = ToUnixTimespan(DateTime.Now),
            end = ToUnixTimespan(DateTime.Now.AddHours(4)),
            url = "www.google.com"
        });
        tasksList.Add(new CalendarDTO
        {
            id = 1,
            title = "Bing search",
            start = ToUnixTimespan(DateTime.Now.AddDays(1)),
            end = ToUnixTimespan(DateTime.Now.AddDays(1).AddHours(4)),
            url = "www.bing.com"
        });

        return Json(tasksList,JsonRequestBehavior.AllowGet);
    }

    private long ToUnixTimespan(DateTime date)
    {
        TimeSpan tspan = date.ToUniversalTime().Subtract(
        new DateTime(1970, 1, 1, 0, 0, 0));

        return (long)Math.Truncate(tspan.TotalSeconds);
    }

    public ActionResult Index()
    {
        return View("Index");
    }

I also have the following code inside head tag in site.master:

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" />
<link href="<%= Url.Content("~/Content/jquery-ui-1.7.2.custom.css") %>" rel="stylesheet" type="text/css" />
<link href="~Perspectiva/Content/Site.css" rel="stylesheet" type="text/css" />
<link href="~Perspectiva/Content/fullcalendar.css" rel="stylesheet" type="text/css" />
<script src="~Perspectiva/Scripts/jquery-1.4.2.js" type="text/javascript"></script>
<script src="~Perspectiva/Scripts/fullcalendar.js" type="text/javascript"></script>
<script src="/Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="/Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>

Everything I did was pretty much copied from http://szahariev.blogspot.com/2009/08/jquery-fullcalendar-and-aspnet-mvc.html

When navigating to /scheduler/calendardata I get a prompt for saving the json data which contents are exactly what I created in the CalendarData function.

What do I need to do in order to render the page correctly?

Thanks in advance,

Eran
