Hi guys i have a small problem i was hoping you could help me with,to put it plainly i have a Template file called Events.cshtml that contains this

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Giantgrandprix.App_Code
@{
Layout = "~/Views/Shared/Master.cshtml";
}
<div class="col-lg-12">
<div class="row eventWrapper">
@Html.Action("Index", "Event", null))
</div>
</div>
<div class="col-lg-12" style="padding: 0px;">
<div id="facebook_sidebar" class="col-lg-2 col-md-12 col-sm-12 col-xs-12 pull-left"><h2>Facebook</h2></div>
<article id="article_master" class="col-lg-6 col-md-12 col-sm-12 col-xs-12 col-lg-offset-1"><h2>Main Content</h2>
</article>
<div id="sponsor_sidebar" class="col-lg-2 col-md-12 col-sm-12 col-xs-12 pull-right"><h2>Sponsorer</h2></div>
</div>
as you can see i am trying to call the Index method within my EventController that has this inside of it

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using Umbraco.Web.Mvc;

namespace Giantgrandprix.Controllers

{

public class EventController : Controller

{

public PartialViewResult Index()

{

return PartialView("Event");

}

and i want it to return this Partial View everytime i call the Index method mostly so i can make a new method later on that will grab the Id i send along, the Partial View i want to call looks like this

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@using Giantgrandprix.App_Code

@foreach (var page in Model.Content.Children.Where(x => x.DocumentTypeAlias == "Event"))

{

var img = Umbraco.TypedMedia(page.GetPropertyValue<string>("image", recurse: true));

<h3>@page.GetPropertyValue("name")</h3>

<p>@Html.ShortText(page.GetPropertyValue("description").ToString(),25)</p>

</div>

</a>

}

I am still new to Umbraco so sorry for any newb mistakes

Hi Casper.

Do you get an error or how do you struggle with your issue?

You might want to read up on how surface controllers work and MVC and umbraco in general. There are a few differences from working

with regular MVC

Best regards

Let your eventcontroller inherit from the surface controller ie:

 public class EventController : SurfaceController

Also check out https://our.umbraco.org/documentation/reference/Templating/Mvc/surface-controllers

Ok so far so good :) only problem i get now is

Object reference not set to an instance of an object.

foreach (var page in Model.Content.Children.Where(x => x.DocumentTypeAlias == "Event"))

You Model is probably empty.

So you might want to return something like:

 return PartialView("Event",new Umbraco.Web.Models.RenderModel(CurrentPage, CultureInfo.CurrentUICulture));

Bingo! That did the trick thanks alot :-D only thing now is i have no idea what you just did. But basically what i want to do is just display events and so on and when a user clicks an event i want to make a getsingleevent method in the controller that takes the id as the parameter and displays other stuff i am guessing this should not be a problem and most of all i am counting on not needing a model for any of this since i am not interacting with the database in any way ? Thanks a lot for the support means a lot to me :)
