How to bind list of string in kendo dropdownlist

Question

Hello I am using Kendo for ASP.NET MVC.

I have list of string containing data

[0]="str1"
[1]="str2"... and so on

Now I want to bind this list of string into kendo dropdownlist.

I have bind dropdownlist by list of class with name and id but with only one data in list of string, I don't know how to bind that!

I have done that like below:

 @(
                 Html.Kendo().DropDownList()
                            .Name("ddlstrings")
                            .DataTextField("stringname")
                            .DataValueField("stringname")
                            //.Events(x => x.Select("sourceclick"))
                            .SelectedIndex(0)
                            .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("getData", "String");
                                    });
                                })
                )

But I got undefined.

I am returning the data like this:

public JsonResult getData()
        {
            try
            {
                List<string> stringlist = object.getstrlist();
                return Json(stringlist, JsonRequestBehavior.AllowGet);
            }
            catch (Exception ex)
            {
                return Json("", JsonRequestBehavior.AllowGet);
            }
        }

Does anyone have any idea how can I do this!

Any help would be appreciate.

The answer you have provided is right actually. The Action must return List<SelectListItem> as the output. See this Example and in the code see the BindTo property.

You can just update your code to below.

        public JsonResult getData()
        {
            try
            {
                var stringlist = object.getstrlist().select( x=> new SelectListItem
                             {
                              Value = x,
                              Text = x
                             }).ToList();


                return Json(stringlist, JsonRequestBehavior.AllowGet);
            }
            catch (Exception ex)
            {
                return Json("", JsonRequestBehavior.AllowGet);
            }
        }

I have just modified your code to not have a for loop.
