unable to get value of the property 'open'

[Paul]

I get this error when using the kendo window. It’s odd because that’s how the examples show on the Telerik Kendo demos (http://demos.kendoui.com/web/window/index.html) and it works, but it will throw this error anyways. I had to download the latest script files for Telerik Kendo UI Web (http://www.telerik.com/account/your-products/internal-builds.aspx) just to even get the window to work.

Error occurs on the .open() in the script to open the kendo window.

What do I need to do to stop having the run time error pop up?

Partial View:

@{
    ViewBag.Title = "User Preferences";
}

<h2>User Preferences</h2>
@(Html.Kendo().Window()
    .Name("winPreferences")
      .Content(Html.Partial("_UserPreferences").ToHtmlString())
      .Title("Edit User Preferences")
      .Draggable()
      .Resizable()
      .Width(500)
 )
<script>


    $("#winPreferences").data("kendowindow").open();


</script>

Using jquery-1.9.0, kendoui.web.2013.1.325.commercial

Hi Paul,

The Kendo UI Widget names are case sensitive and you should change your code like this to get it working:
$("#winPreferences").data("kendoWindow").open();
