    I am evaluating the kendo controls for purchase and I am having trouble setting a kendo dropdown to readonly in mvc 4 using the razor view engine. I keep getting the error

    0x800a01b6 - Microsoft JScript runtime error: Object doesn't support property or method 'readonly'

    My solution is a little more complex but basically I have the below code with a bunch of stuff cut out. Everything works fine until i want to set the dropdown to read only on page load in one of my cases. It seems like I am following the documentation but i can't see to figure out what is wrong.  I've spent a good few hours on this and am out of tricks. I've got access to the dropdown for click events that i set on buttons and such but not during the $(document).ready.

    I feel like something in .readonly() is using something not in my jquery but that is only a wild guess.

    Thanks in a advance

    //.readonly()doesn't work
      $(document).ready(function () {
            var something = $("#ProvinceRegion").data("kendoDropDownList");

    //note: something.enable(false); works here just readonly() doesn't


    //notice I can set .enabled on this function below
        function ClearCustomerClick() {

    //all the below work
            var dropdownlist = $("#CustomerName").data("kendoDropDownList")
            var billContactList = $("#BillingContact").data("kendoDropDownList")
            var billSiteList = $("#BillSite").data("kendoDropDownList")



    and then my dropdown list is below

    @using (Html.BeginForm("ProjectSetupDetails", "Setup", FormMethod.Post, new { enctype = "multipart/form-data" }))
                            .OptionLabel("Pick a region...")

    Hello Tim,

    The readonly functionality is available since Q1 2013 (2013.1.319). Before this release the widgets did not have support for readonly. Please verify that you are using the latest official release of Kendo UI.
    Check this jsBin demo, which shows how to use readonly method.

    Thanks for your reply.

    I am currently using the 2012.3.1114.340 for Kendo.MVC dll. I will look into updating the to the latest version to see if I can get readonly to work.

    **Update: Georgi's solution worked

    Is there any way to set a kendo dropdown to readonly when using the mvc razor html helpers to generate the control?

    All the threads I have found only show examples doing it with the javascript function, but surely there must be a way to do this with razor in c#.

    You can use the following approach to achieve this requirement:
    .HtmlAttributes(new { style = "width:50%", @readonly = "readonly" })

    I hope this will prove helpful.
