    Error when rendering grid

    Hi, i am getting an annoying error, when trying to render an umbraco grid..

    I have another solution where it works perfectly and exactly as this solution is made.

    i am running umbraco 7.6

    my code:

    My Controller :

    namespace Carinas_Univers.Controllers
    {
        public class TextPageController : MasterController
        {
            // GET: TextPage
            public ActionResult TextPage()
            {
                var model = new TextPageViewModel();
    
                //GridDataModel grid = CurrentPage.GetPropertyValue<HtmlString>("textPageGrid");
                // GET grid 1
                var textPageGrid = CurrentPage.GetGridHtml(DocTypes.TextPage.TextPageGrid);
                //add to model.
                model.TextPageGrid = new HtmlString(textPageGrid.ToHtmlString());
    
    
                return View(model);
            }
        }
    }
    

    The error is on var textPageGrid

    I am Getting This error:

    I Hope there is someone that can help me figure this out..

    i guess yes ? But how do i determine if it works "correct" ?

    Edit

    As far as i can see it should work correctly, i can access properties like bodytext and such without issue..

    Andre, did you read this - https://our.umbraco.org/documentation/getting-started/backoffice/property-editors/built-in-property-editors/grid-layout/render-grid-in-template

    Finally the Html.GetGridHtml helpers are the recommended approach for rendering grid properties in templates, however you may see in grid examples or discover in your existing site 'legacy code' when using the 'dynamic' CurrentPage approach for working with Umbraco templates and grid properties:

    @CurrentPage.GetGridHtml(Html, "propertyAlias")
    @CurrentPage.GetGridHtml(Html, "propertyAlias", "bootstrap2")
    @CurrentPage.GetGridHtml(Html, "propertyAlias", "mycustomrenderer")
    @CurrentPage.GetGridHtml(Html, "propertyAlias", "/views/mycustomrenderer.cshtml")
    

    These approaches are considered obsolete. Use @Html.GetGridHtml.

    Can you try insert in your view:

    @Html.GetGridHtml(DocTypes.TextPage.TextPageGrid)?

    This is my view now.

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<Carinas_Univers.Models.TextPageViewModel>
    
    @{
        Layout = "Master.cshtml";
    }
    
    <!-- Main -->
    <div class="main">
        <h1>Velkommen til TextPage Dokumentet.</h1>
    
    
        <!-- Grid Layout here -->
    
        @Html.GetGridHtml(DocTypes.TextPage.TextPageGrid)
    
    </div>
    @Html.Partial("_Sidebar")
    

    But i get the error does not contain a definition for getgridhtml.

    What about this code:

    @Html.GetGridHtml(Umbraco.AssignedContentItem, "propertyAlias")

    As far as i can see, i have the same references as my other project, which is also what i find so confusing...

    Did you find some issues?

    Maybe some caching, how are you running the website?

    I am running the website locally with a database running locally as well on management studio 2017.

    I have tried removing everything in app_data, without any success.

    Your views are most likely located in the ~/Views/ folder (or a sub folder), and as such they need ~/Views/Web.config to work properly. Are you by any chance missing this file? I think I've seen similar errors when this particular Web.config file hasn't been deployed to the live server.

    To explain it a little bit further, ~/Views/Web.config comes with Umbraco and is responsible for setting the namespaces that ASP.NET should import by default in your views - eg. the UmbracoViewPage class that you're missing, is located in the Umbraco.Web.Mvc namespace, which should be imported by default.

    Should your views are located elsewhere, you should probably add a similar Web.config file in that folder - or import the namespaces manually.

    I hope that helps ;)
