ambiguous bindto

[Bart]

Hi,

I'm trying to create a dropdown into a gridview, and I have tried lots op things.
the thing I'm stuck with now is this error

"The call is ambiguous between the following methods or properties: 'Kendo.Mvc.UI.Fluent.DropDownListBuilder.BindTo(System.Collections.Generic.IEnumerable<Kendo.Mvc.UI.DropDownListItem>)' and 'Kendo.Mvc.UI.Fluent.DropDownListBuilder.BindTo(System.Collections.Generic.IEnumerable<System.Web.Mvc.SelectListItem>)'"

in the Bindto I have a list of items which I load from the viewbag.

But I can't get pass this error.
do U need to unreference something?
thank you.

Hi,

Could you provide the code that you are using for the dropdownlist and to add the ViewBag entry? The error indicates the ViewBag entry is not set or is set to null.

Hi Daniel,

I have changed the source now so the dropdownlist is static, but it's not as it should be off course.

what I had was the following
in shared views I have a folder with EditorTemplates and in it I have this template "StatusDdl.cshtml"

@using Kendo.Mvc.UI;
@model int

@(Html.Kendo().DropDownList()
    .Name("Status")
    .Value(Model.ToString())
    .SelectedIndex(0)
    .BindTo(ViewBag.StatusDdl)
    .HtmlAttributes(new { style = "width:250px" })
    .ValuePrimitive(true)
)

the controller looks as following:

public ActionResult Users_Read([DataSourceRequest]DataSourceRequest request)
        {
            List<UserStatus> UserStatus = db.UserStatus.ToList();
            ViewBag.StatusDdl = UserStatus;


            IQueryable<Users> users = db.Users;
            DataSourceResult result = users.ToDataSourceResult(request, user => new {
                Id = user.Id,
                UserId = user.UserId,
                Name = user.Name,
                Email = user.Email,
                Password = user.Password,
                Status = user.Status,
                //UserStatus = new Teunesen_Bestandsbeheer.Models.UserStatus()
                //{
                //    Id = user.UserStatus.Id,
                //    Status = user.UserStatus.Status
                //},
                Admin = user.Admin,
                Language = user.Language,
            });

            return Json(result);
        }

where ViewBag.StatusDdl is the past which is used in the view.

and the view itself looks like this.

  @(Html.Kendo().Grid<Teunesen_Bestandsbeheer.Models.Users>()
                  .Name("grid")
                  .Columns(columns =>
                  {
                  columns.Bound(c => c.Name).Title("Naam").HtmlAttributes(new { @class = "edit-col" });
                  columns.Bound(c => c.Email).Title("Email").HtmlAttributes(new { @class = "edit-col" });
                  //columns.ForeignKey(c => c.Status, (System.Collections.IEnumerable)ViewData["UserStatus"], "Id", "Status");
                  columns.Bound(c => c.Status).Title("Status").HtmlAttributes(new { @class = "lock-col" }).EditorTemplateName("StatusDdl").Width(270);
            columns.Bound(c => c.Admin).ClientTemplate(
      "<input type='checkbox' value='#= Id #' " +
          "# if (Admin) { #" +
              "checked='checked'" +
          "# } #" +
      "/>"
);

where the partialview is used as editor template.

The viewbag however is filled, that I'm sure of, but I think maybe I need to specify a type or something but I can't figure it out.

Hi again,

From the code it seems that the ViewBag is populated in the DataSource Read action and not the action used to Render the View with the grid. Thus the ViewBag entry will not be available at the time the grid and its editors are rendered. Please try moving the code to set the ViewBag entry in the action that returns the View with the grid.

thnx,

That's it

User control like this

public ActionResult Index()
       {
           ViewData["UserStatus"] = db.UserStatus;
           var UserStatus = db.UserStatus.Select(x => new SelectListItem { Value = x.Id.ToString(), Text = x.Status }).ToList();
           ViewBag.StatusDdl = UserStatus;
           return View();
       }

and then in the view this

columns.ForeignKey(c => c.Status, (System.Collections.IEnumerable)ViewData["UserStatus"], "Id", "Status").EditorTemplateName("StatusDdl").Width(270);

and that was it.
