 [httppost]     public actionresult createagreement(modelb modelb)     {         if (modelstate.isvalid)         {             return view("start", modelb);         }         return view("start", modelb);     }     [httppost]     public actionresult test(modela modela)     {         if (modelstate.isvalid)         {             return view("start", modela);         }         return view("start", modela);     }     public actionresult start()     {         return view();     }     public actionresult firstview()     {         modela obja = new modela();         return partialview("_partiala", obja);     }     public actionresult secondview()     {         modelb objb = new modelb();         return partialview("_partialb", objb);     } 

now not getting error message on click of button..and thing..is both view getting opened up..on click of button..how prevent that?

to validate form check these steps :

1) partial view set layout null :

@{     layout = null; } 

2) add these scripts before form :

<script src="@url.content("~/scripts/jquery.validate.min.js")"></script> <script src="@url.content("~/scripts/jquery.validate.unobtrusive.min.js")"></script>  @using (html.beginform("createagreement", "home"))  { 

3) add html validation :

@using (html.beginform("createagreement", "home"))  {      @html.validationsummary(true) 

4) if have annotation model , error message works.
