Asp.Net Mvc 3 Client Validation, Attributes generation

Question

Asp.net Mvc3 ads some custom attributes like \"data-val-required\" on input elements to perform validation. I know all theory behind this, how it works.

What i want to k

Answer 1

I believe BeginForm method internally assigns a formcontext object to viewCotnext's property FormContext. If you do not want to use plain html form tags you have to do it manually like

<%
    this.ViewContext.FormContext = new FormContext();
%>

and in razor it would probably be

@{
    this.ViewContext.FormContext = new FormContext();
}

Answer 2

Problem here is that internally Html.BeginForm is flagged by Html.EnableClientValidation() to create FormContext that will store client-side validation metadata. Now, any HTML helper method that renders validation message also registers appropriate client-side validation metadata in FormContext. The result is what you get if you use helper. However, if you try to use HTML syntax and not helpers, the FormContext is never registered and therefore your validation is never added.
