    it's been some hours that i have been trying to display a dropdownlist in my grid instead of the numeric textfield that appears for a specific column ( which is a foreign key).

    When i click on the edit button, this column displays a textfield with the possibility to select the ID only. I want the name instead.

    This is my code:

     PS: the rows displayed in my grid are NoteForm objects and the foreign key i'm talking about is languageId ( the table is language)

      public class NoteForm
          [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
          [Display(Name = "Title")]
          public string Title { get; set; }
          [Display(Name = "Text")]
          public string Text { get; set; }
          [Display(Name = "Language")] 
          public int languageId { get; set; }
          [UIHint("LangDropDown")]<!--- I TRIED TO ADD THIS ATTRIBUTE -->
          public virtual Language language { get; set; }
          public int id { get; set; }
          public int userId { get; set; }
      public class Language
          public string lang { get; set; }
          public int id { get; set; }

    My View:


    @using Kendo.Mvc.UI
    @model DevelopmentNotesProject.Models.NoteForm
        ViewBag.Title = "Index";
    <script type="text/javascript">
        function formatter(value) {
            return value.substring(0, 50);
    <section id="listing">
        <h2>My Notes</h2>
            .Columns(columns =>
                columns.Bound(c => c.Title).Width(160).ClientTemplate(string.Format("{0}...", "#= formatter(Title) #"));
                columns.Bound(c => c.Text).Width(450).ClientTemplate(string.Format("{0}...", "#= formatter(Text) #"));
                columns.ForeignKey(p => p.languageId, (System.Collections.IEnumerable)ViewData["lang"], "Id", "Name").Title("Language").Width(140).EditorTemplateName("LangDropDown"); <!--LangDropDown is the name of my partial view i have created in the Shared/Partial folder-->
                columns.Command(command => { command.Edit(); command.Destroy(); });
            .HtmlAttributes(new { style = "height: 380px;" })
            .Pageable(pageable => pageable
             .DataSource(dataSource => dataSource // Configure the grid data source
                      .Ajax() // Specify that ajax binding is used
                      .Read(read => read.Action("Notes_Read", "MyNotes")) // Set the action method which will return the data in JSON format
                      .Destroy(update => update.Action("Notes_Destroy", "MyNotes"))
                      .Update(update => update.Action("Notes_Update", "MyNotes"))
                      .Model(model =>
                              model.Id(p => p.id);
    @Html.ActionLink("Add a new note", "Add", "MyNotes")
     @section Scripts {

    My partial View:

    @using Kendo.Mvc.UI



    public ActionResult Index()
        var dbo = new UsersContext();
        ViewData["lang"] = dbo.Language.Select(b => new { Id = b.id, Name = b.lang });
        return View();

    Thanks a lot for your help

    Hi Fiery,

    From the provided information it seems that the following points might be related to current behavior:
    • Editor templates should be nested inside "~/Views/Shared/EditorTemplates" folder - please make sure the editors are correctly nested inside this folder. More information is available in this help article.
    • Editor name should be the same as field name (even better approach would be to use strongly type DropDownListFor builder) - currently the editor name is set invalidly to another field: 
      @using Kendo.Mvc.UI
