Please consider adding a short-hand method to set the id of form element widgets such as:
Html.Kendo().DatePicker().Name("StartDate").Id("FormA_StartDate");

The code above looks a lot cleaner and more fluent and the one below.
Html.Kendo().DatePicker().Name("StartDate").HtmlAttributes( new { id = "FormA_StartDate"} );

This really comes in handy when building large single page application (SPA) where many entry forms are loaded onto a single page. Manually setting the Id property for widget elements help avoid potential html elements' id conflicts when we have Kendo form widgets of the same name.
