how to set a default value to kendo ui dropdown?

I am using a kendo UI DropDownList control, how can we set a default value to the DropDownList?

I have a selected list property in viewmodel as following :

public SelectList AuditTypes { get; set; }

Then in controller I am populating the selected list and setting it to a default value

viewModel.AuditTypes = new SelectList(dropdownDetails, "Value", "Text", dropdownDetails.Where(x => x.Default == true));

and in my razor view I have the following code :

  @(Html.Kendo().DropDownList()
                    .Name("AuditType")
                    .DataTextField("Text")
                    .DataValueField("Value")
                    .BindTo(Model.AuditTypes)                     
                    .AutoBind(true)

The problem is that the default value is not being set.
