Ajax Binding return 'undefined' results in list

[Jeff]

Hi,

I'm not able to get Ajax binding to work with my combobox.  I went the Kendo Ajax binding example to the letter.  The combox box returns 'undefined' in the results.  I verified that the controller method is called.

Controller:

public JsonResult GetContainers()

        {

            List<Container> containers = new List<Container>();

            containers.Add(new Container() { ContainerId = 1, ContainerName = "Container1" });

            containers.Add(new Container() { ContainerId = 2, ContainerName = "Container2" });

  

            return Json(containers);

        }

View:

    @(Html.Kendo().ComboBox()

        .Name("TestContainerName")

        .DataTextField("ContainerName")

        .DataValueField("ContainerId")

        .Filter(FilterType.Contains)

            .DataSource(dataSource =>

            {

                dataSource.Read(read =>

                    {

                        read.Action("GetContainers", "Common");

                    });

            })

        .SelectedIndex(0)

)

Hello Jeff,

 
The only thing I can spot in the code snippet is the missing second parameter in the Json method. By default the DataSource makes GET requests to the server and you will need to allow these requests:

return Json(containers, JsonRequestBehavior.AllowGet);

If the problem still persist I will need a repro test project.

I had the same problem.  If you look at the json being returned you'll see it returns Text and Value not your property names.  I can't figure out why though.

This post and Karl's answer helped me a LOT today.  Thanks!
