asp.net mvc - Display a list in a view MVC 4 -

i have model course, model component , model evaluation:

public class course  {    public virtual int courseid { get; set; }    public virtual string name { get; set; }    public virtual list<component> components { get; set; }    public virtual list<userprofile> users { get; set; }    public virtual list<evaluation> evaluation { get; set; }  }  public class component  {    public virtual int componentid { get; set; }    public virtual int courseid { get; set; }    public virtual course course { get; set; }    public virtual string namecomp { get; set; }  }  public class evaluation {     public virtual int evaluationid { get; set; }     public virtual int courseid { get; set; }    public virtual course course { get; set; }     public virtual int userid { get; set; }    public virtual userprofile user { get; set; }     public virtual int grade { get; set; } } 

i need show in view table users, components created , grade each one. tried way:

@model sgp.models.course  <table> <tr>     <th>         username     </th>     @foreach (var x in model.components)     {         <th>             @html.displayfor(modelitem => x.namecomp)         </th>     }     <th></th> </tr>  @foreach (var item in model.evaluation) {     <tr>         <td>             @html.displayfor(modelitem => item.user.username)         </td>         @foreach (var x in model.components)         {              <td>                 @html.displayfor(modelitem => item.grade)             </td>         }         <td>          </td>     </tr> } 

but gives me components in 1 column, , need 1 column each component, , grade each one:

the code have gives this:

username - component1component2component3    test  -              12     test  -              13    test  -              10 (example of result username , grades) 

and need:

username - component1 - component2 - component3   test   -    12      -    13      -    10  (example of result username , grades) 

how can this? thanks

the definition of evaluations in course should be:

public virtual igrouping<string, evaluation> evaluations { get; set; } 

the code should be:

@model sgp.models.course  <table> <tr>     <th>         username     </th>     <th>     @foreach (var x in model.components)     {         @html.displayfor(modelitem => x.namecomp)     }     </th>     <th></th> </tr> @foreach (var group in model.evaluations) { <tr>     <td>        @html.displayfor(modelitem => group.key)     </td>     @foreach (var item in group)     {         <td>           @html.displayfor(modelitem => item.grade)         </td>      }     <td>     </td> } </tr>
