asp.net mvc - Partial Views & ModelState.AddModelError -

the source of loginregister view :

@html.partial("authentication/_login") @html.partial("authentication/_register")

and each child view has got form syntax

@using (html.beginform(**seperated-methods**, "login"))  {     @html.validationsummary(false) }

i send error(s) in postback whit code

modelstate.addmodelerror("", "**any-error-message**"); return view("authentication/loginregister", customized-data);

the point , error message shows in both partial views.

you need tell modelstate property error refer to:

modelstate.addmodelerror("propertyname", "**any-error-message**");

now in

@html.validationmessagefor(m => m.propertyname)

if don't specify property name, error considered global , shown in every validationsummary.
