I want to have the dropdown default select a value.  I have the value is in a ViewData.  How can I access this from javascript?

@(Html.Kendo().DropDownList()
                       .Name("locationCode")
                       .HtmlAttributes(new { style = "width:200px" })
                       .DataValueField("Code")
                       .DataTextField("Name")
                       .DataSource(source =>
                                    {
                                        source.Read(read =>
                                        {
                                            read.Action("GetUserGlobalDimensions", "RequestPONumber");
                                        });
                                    }

                                  )
                        .Events(e => { e.DataBound("onLocationDataBound"); })

In js file:
function onLocationDataBound() {
    this.value('ViewData["defaultLocationValue"]');
}

Thanks in advance.

Hello Greg,

I would suggest you use the Value method that will set the widget's option value. This will select the corresponding data item on load:
@(Html.Kendo().DropDownList()
                       .Name("locationCode")
                       .HtmlAttributes(new { style = "width:200px" })
                       .DataValueField("Code")
                       .DataTextField("Name")
                       .DataSource(source =>
                                    {
                                        source.Read(read =>
                                        {
                                            read.Action("GetUserGlobalDimensions", "RequestPONumber");
                                        });
                                    }
 
                                  )
                        .Events(e => { e.DataBound("onLocationDataBound"); })
                        .Value(ViewData["defaultLocationValue"])
)

Let me know if I am missing something.

Thanks  using it as: .Value(ViewData["defaultLocationValue"].ToString())

Did the trick.
