asp.net mvc - Difference between Html Validate and Html ValidateFor -

why use validate , validatefor in validation? using that, not getting error message in ui.

code

   <div>     @{html.beginform();}     @html.textboxfor(x => x.lastname, new { id = "txtlastname" })     @{html.validate("lastname");}     @{html.validatefor(x=>x.lastname);}     <input type="submit" id="btnsubmit" value="submit" />     @{html.endform();} </div> 

this behavior intentional. both these helpers register corresponding parameters client-side validation, without showing message should validation fail. message can still displayed in validationsummary.

if want show message specific field/parameter, should use validationmessage or validationmessagefor instead:

@html.validationmessage("lastname") @html.validationmessagefor(x=>x.lastname)
