c# - Model is null in controller even after fixing get set in model definition -

i had application weakly typed , decided best change typed... running issues.

my controller delivers new model razor view (which has small form in it). use textboxfor(model => mymodel.type) , post controller. can see post has needed values once hits controller model null.

 [httpget]         public actionresult login(int op)         {                     loginwrapperclass newoperation = new loginwrapperclass();                     newoperation.newl = new epsdb();                     newoperation.newp = new ep(op, request.cookies["state"].value);                     return view(newoperation);             }    [httppost, validateinput(true)]         public actionresult login(loginwrapperclass newoperation)         {             if (modelstate.isvalid)             {                 newoperation.lookup();                 if (newoperation.newp != null)                 {                     //stuff                      return redirecttoaction("recordop", "authenticated", newoperation.newp);                 }             } 

view:

@model webapp.models.loginwrapperclass  @{     viewbag.title = "operation"; }  <div id="indexop" class="textcenter">     <div id="time"></div>     <div id="loader" class="hiddenandgone"><img src="~/content/images/loader.gif"></div>     <div id="operations">         @using (html.beginform())         {             //html.antiforgerytoken();             <div class="ops">                 <div>                     @html.textboxfor(model => model.newl.badge_nbr, new { @id = "badge_nbr", @class = "readfont", autofocus = "autofocus", autocomplete = "off", placeholder = "" })                     @html.textboxfor(model => model.newp.punch_type, new { type="number", @class = "hidden" })                 </div>                 <div id="submit" class="hidden">                     <input type="submit" value="validate" class="validatesubmit"  />                 </div>             </div>         }     </div> </div> 

basically, through fiddler, can see post contains values need controller's model null. why?

what posting this: newl.badge_nbr=18845733&newp.punch_type=1

i adding class declarations here:

 public class loginwrapperclass     {         public epsdb newl { get; set; } //fixed per aaron's response... still no binding         public ep newp{ get; set; }         public void lookup()         {             using (var db = new pstestentities())             {                 ienumerable<epsdb> foundindb;                 foundindb = db.epsdbs.where(founde => this.newl.badge_nbr.tostring() == founde.badge_nbr.tostring().substring(3));                  if (foundindb.count() > 0)                 {                      this.newl = foundindb.first();                     this.newp.badge_nbr = this.newl.badge_nbr;                     this.newp.emplid = this.newl.emplid;                 }             }         }     } //this partial class added of     public partial class epsdb         {             [key]             public int p_key { get; set; }             public int emplid { get; set; }             [required]             public long badge_nbr { get; set; }             public nullable<system.datetime> birthdate { get; set; }             public string name { get; set; }         }      public partial class ep     {         [required]         public long badge_nbr { get; set; }         [required]         public int emplid { get; set; }         [required]         public system.datetimeoffset punch_dttm { get; set; }         [required]         public int punch_type { get; set; }         public nullable<double> tl_quantity { get; set; }         [key]         public long p_key { get; set; }     }  public partial class ep     {         [notmapped]         public bool containsquestions = false;         [notmapped]         public list<question> questions { get; set; }         public ep(int punchtype, string state)         {             punch_dttm = datetimeoffset.utcnow;             punch_type = punchtype;             if((punchtype == 1 || punchtype == 2) & containsquestions)                 questions = getquestions(state, punchtype);         }     private list<question> getquestions(string state, int punchtype){         list<question> questions = new list<question>();       //do stuff       return questions      }         ///plus other methods not used in controller/view     } public class question     {         public string questionname { get; set; }         public string questionstring { get; set; }         public int answer { get; set; }     } 

you suffering believe: asp.net mvc - model binding excludes class fields?

you have declaration using fields:

public class loginwrapperclass {     public epsdb newl;     public ep newp;     //... } 

but need using properties:

public class loginwrapperclass {     public epsdb newl {get;set;}     public ep newp {get;set;}     //... }
