Question

I am currently trying to figure out KendoUI. I am using version 2012.1.322.

I have a simple array of strings List<string> returned back to the user in a web method through an AJAX call.

["name","phone","address","zip"]

When the ListView binds the list is empty, I only get

<ul id="fileAlist" data-role="listview" class="k-widget k-listview"></ul>.

I’m pretty sure it has to do with my template being wrong. What do I have to set instead of ${Object} to get it to render like:

<ul id="fileAlist" data-role="listview" class="k-widget k-listview">
  <li>name</li>
  <li>phone</li>
  <li>address</li>
  <li>zip</li>
</ul>

Here is the current code:

 $(document).ready(function () {
     $("#fileAlist").kendoListView({
         template: "<li>${Object}</li>",
         dataSource:
             new kendo.data.DataSource({
                 transport: {
                     read: {
                         url: '@Url.Action("GetColumnNames", new {File="A"})',
                         dataType: "json",
                         type: "POST",
                         contentType: "application/json; charset=utf-8"
                     }
                 }
             })
     });
 });

C# Code (in-case you’re interested)

    [HttpGet]
    public JsonResult GetColumnNames(string file)
    {
        if (file == "A")
        {
            var columns = new List<string>()
                              {
                                  "name",
                                  "phone",
                                  "address",
                                  "zip"
                              };
        }

        return new JsonResult { Data = columns, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
    }

Some other trial and fails
Here are some of the template ideas I tried and the results that came back. Obviously they all didn’t give me the string output I wanted.

• I tried changing the template to be template: "<li>${}</li>" and when rendered I get <li>undefined</li>
• I tried changing the tempalte to be template: "<li>$.val()</li>" and when rendered I get <li>$.val()</li>
• I tried changing the tempalte to be template: "<li>${}.selector</li>" and when rendered I get <li>undefined.selector</li>

There are several configuration issues in your code. I’ve simplified the code a bit to concentrate on a working example.

Model class:

public class Contact
{
    public int ContactId { get; set; }
    public string Name { get; set; }
    public string Phone { get; set; }
    public string Address { get; set; }
    public string Zip { get; set; }
}

View markup, you’ll need to play with the list layout to get the desired look:

<ul>
    <div id="contactList" style="width: 400px;"></div>
</ul>

Note how the template mark up looks like:

<script id="template" type="text/x-kendo-tmpl">
    <li>${ Name} ${ Phone } ${ Address } ${ Zip }</li>
</script>

<script type="text/javascript" >
    $(document).ready(function () {
        var datasource = new kendo.data.DataSource({
            transport: {
                        read: {
                          url: "@(Url.Action("GetContacts", "Home"))",
                          dataType: "json",  //switched to json instead of jsonp for this example
                          contentType: "application/json; charset=utf-8",
                          type: "GET"
                       }
           }
       });

       $("#contactList").kendoListView({
          dataSource: datasource,
          template: kendo.template($("#template").html())  //Link the template to the list view control
       });
   });

Controller that return json:

public ActionResult GetContacts()
{
    List<Contact> list = new List<Contact>();
    Contact contact = new Contact() { ContactId = 0, Name = "Steve", Address = "Some Street", Phone = "1-345-345-3455", Zip = "334566" };
    list.Add(contact);
    contact = new Contact() { ContactId = 1, Name = "Jim", Address = "Another Street", Phone = "1-777-987-3889", Zip = "998754" };
    list.Add(contact);

    return Json(list, JsonRequestBehavior.AllowGet);
}

–EDIT–

Here is a controller that’ll return a json string without a concrete Contact object.

public ActionResult GetContacts()
{
    var columns = new List<Dictionary<string, object>>() {
        new Dictionary<string,object>(){ {"Name", "Rex"}, {"Phone", "1-123-123-2342"}, {"Address", "Westwood Drive"}, {"Zip", 928347}},
        new Dictionary<string,object>(){ {"Name", "Smith"}, {"Phone", "1-333-444-5555"}, {"Address", "Allen Way"}, {"Zip", 23456}}
    };

    return Json(columns, JsonRequestBehavior.AllowGet);
}
