Dear KendoUI Team!
In one of my Views I alwas get a javascript error when I leave the focus of the Dropdownlist.

The error occurs in parseJSON in this line:
{return e.JSON&&e.JSON.parse?e.JSON.parse(n):null===n?n:"string"==typeof n&&(n=b.trim(n),n&&k.test(n.replace(S,"@").replace(A,"]").replace(E,"")))?Function("return "+n)():(b.error("Invalid JSON: "+n),t)}

The Model looks like this:
[Required]
[LocalizedDisplayName("Language")]
public int PreferredLanguageId { get; set; }

And the cshtml is here:

div class="type-text">
@(Html.Kendo().DropDownListFor(m => m.PreferredLanguageId)
.Name("PreferredLanguageId")
.SelectedIndex(Model.PreferredLanguageId)
.BindTo(LeoHelper.GetLanguages())
.DataTextField("Text")
.DataValueField("Value")
)
</div>

Although the javascript Exception is thrown, the value is correctly saved.

Hi, I have the same problem and I'm very interested to know how to fix this. I cannot provide a runable project but I can give you the following information:

Here's the JSON object I caught with firebug: [{"salesgeoid":5,"shortname":"ALL"},{"salesgeoid":1,"shortname":"BRA"},{"salesgeoid":3,"shortname":"CHE"},{"salesgeoid":2,"shortname":"FRA"}]

Here's my view:

<div class="editor-field">@(Html.Kendo().DropDownListFor(model => model.salesgeoid)

.Name("salesgeo")

.HtmlAttributes(new { style = "width:150px" })

.DataTextField("shortname")

.DataValueField("salesgeoid")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("SalesGeoList", "Profile");

});

}))</div>

And my controller:

public JsonResult SalesGeoList()

{

return Json(db.SalesGeo.Select(x => new { salesgeoid = x.salesgeoid, shortname = x.shortname }), JsonRequestBehavior.AllowGet);

}

Your help would be greatly appreciated.
