<form asp-controller="postes" asp-action="create" method="post" id="formps" role="form"> @html.antiforgerytoken()  <div class="form-horizontal">     <h4>postes</h4>     <hr />     @html.validationsummary(true, "", new { @class = "text-danger" })      <div class="form-group">         @html.labelfor(model => model.idproduit, "produit", htmlattributes: new {@class = "control-label col-md-2"})         <div class="col-md-10">             @html.dropdownlist("idproduit", null, htmlattributes: new {@class = "form-control"})             @html.validationmessagefor(model => model.idatelier, "", new {@class = "text-danger"})         </div>     </div>      <div class="form-group">         @html.labelfor(model => model.idatelier, "atelier", htmlattributes: new { @class = "control-label col-md-2" })         <div class="col-md-10">             @html.dropdownlist("idatelier", null, htmlattributes: new { @class = "form-control" })             @html.validationmessagefor(model => model.idatelier, "", new { @class = "text-danger" })         </div>     </div>      <div class="form-group">         @html.labelfor(model => model.designationposte, htmlattributes: new { @class = "control-label col-md-2" })         <div class="col-md-10">             @html.editorfor(model => model.designationposte, new { htmlattributes = new { @class = "form-control" } })             @html.validationmessagefor(model => model.designationposte, "", new { @class = "text-danger" })         </div>     </div>      <div class="form-group">         <div class="col-md-offset-2 col-md-10">             <input type="submit" value="create" class="btn btn-default" />         </div>     </div>  </div>  } 

my product controller:

 public actionresult create([bind(include = "idproduit,idpole,reference,designationproduit")] produits produits)     {         if (modelstate.isvalid)         {             db.produits.add(produits);             db.savechanges();             return redirecttoaction("index");         }          viewbag.idpole = new selectlist(db.pole, "id", "designation", produits.idpole);         return view(produits);     } 

my post controller:

 public actionresult create(postes postes)     {         if (modelstate.isvalid)         {             db.postes.add(postes);             db.savechanges();             return redirecttoaction("index");         }          viewbag.idatelier = new selectlist(db.atelier, "id", "designationatelier", postes.idatelier);         viewbag.idproduit = new selectlist(db.produits, "idproduit", "designationproduit", postes.idproduit);         return view();     } 

i want pass idproduit other form, idproduit not manually added.
