Can't get a correct DateTime from querystring

Question

I'm pretty new to C# and MVC coding. I'm making a booking application and I'm using DayPilotMonth for a calendar. I'm using the following code in my view:

    @Html.DayPilotMonth("dpm", new DayPilotMonthConfig
{
BackendUrl = Url.Content("~/Home/Backend"),
TimeRangeSelectedHandling = DayPilot.Web.Mvc.Events.Month.TimeRangeSelectedHandlingType.JavaScript,
TimeRangeSelectedJavaScript = "document.location='Bokabord2?startingtime={0}';"})

According to someone on DayPilot the {0} in TimeRangeSelectedJavaScript gives the clicked date in DateTime format.

Now when I'm trying to use the 'startingtime' in my controller nothing works. It seems like the value is always null and I can't find a way to convert it. This is the code I have been trying to use:

     public ActionResult Bokabord2(DateTime? startingtime)
    {

        DateTime startingTime;
        if (Session["InloggatId"] != null)
        {


            if (Request.QueryString["startingtime"] != null)
            {

               startingTime = Convert.ToDateTime(Request.QueryString["startingtime"]);


                ViewBag.Message2 = startingtime;
            }
            else
            {
                ViewBag.Message2 = "Error";
            }
            return View();
        }
        else
        {
            return RedirectToAction("Login", "Account");
        }

    }

When I run the application the error message always shows up at the Convert.ToDateTime line and says something about string not able to convert to DateTime.

Thanks in advance Regards Philip

If you use DateTime type, so your value will be like *02/02/2016 02:02:02.123*, right? So, as you can see, you have a space in your url, so it will not work. I might be mistaking, as you may use url encoding, but just wrote my suppose — Khazratbek, Mar 14 '16 at 02:10

protected void builtyLinkButton_click(object sender, EventArgs e)
{
    LinkButton lnk = (LinkButton)sender;
    GridViewRow row = (GridViewRow)lnk.NamingContainer;
    Label l1 = (Label)row.FindControl("Lbl_id");
    Response.Redirect("Loading_request.aspx?Id=" + (l1.Text) + "&Date=" +  (DateTime.Now.ToString()));
}

I just got it to work. The problem was in the View. I had to change

TimeRangeSelectedJavaScript = "document.location='Bokabord2?startingtime={0}';"

To:

TimeRangeSelectedJavaScript = "document.location='Bokabord2?startingtime=' + start;"

Now it sends a string with the selected date to the controller. There is very little information about the functions of DayPilotMonth on their website, hence why I couldn't find anything about it. Thanks all.
