Extend Kendo HtmlHelpers for TextBoxFor

Question

I am looking for how to extend Kendo HtmlHelpers to do something like

@Html.Kendo().TextBoxFor(model => model.field) 

Answer 1

The new version of the Kendo UI interface (2014.2.716) has this extension and much more ...

Answer 2

This is my suggestion.
