I have a template with field of type treelist which holds images, i want to read this field in my view rendering (.cshtml file) and loop over the images and display each one in an tag. How can i do that?

Here is my code for reading from treelist: (this code was working fine when my view was a controller rendering, however when i tried to add a view rendering it gives me error: Inner Exception: The model item passed into the dictionary is of type 'Sitecore.Mvc.Presentation.RenderingModel', but this dictionary requires a model item of type 'Sitecore.Data.Items.Item'. )

@model Sitecore.Data.Items.Item
@using Sitecore.Data.Fields
@using Sitecore.Data.Items
@using Sitecore.Resources.Media
    Layout = null;

                IEnumerable<Item> heroImages = null;
                var heroImagesField = new MultilistField(
                Model.Fields["Hero Images"]);
                if (heroImagesField != null)
                    heroImages = heroImagesField.GetItems();
                if (heroImages != null)
                    int i = 1;
                    foreach (var image in heroImages)
                        var mediaItem = (MediaItem)image;
                        <div class="item @(i == 1 ? "active" : "") ">
                            <img src=" @MediaManager.GetMediaUrl(mediaItem) "
                                 style="width:1920px;" />

  • Why move from a controller rendering to a view rendering? – Chris Auer May 28 '18 at 0:13

You should use the Sitecore.Mvc.Presentation.RenderingModel as your model and then retrieve a Sitecore context item from it, rather then defining the Sitecore.Data.Items.Item as a model.

So, you should change your model definition to this:

@model Sitecore.Mvc.Presentation.RenderingModel

P.S. Your question is covered quite well by this community forum q/a: https://community.sitecore.net/developers/f/8/t/109

Personally, I recommend looking through the community forum or Sitecore KB before submitting a question.
