C# MVC List and Create in same view

I have a model like this

public class Roles
{
     [Key]
     public string RoleId {get;set;}
     public string RoleName {get;set;}
}

The challenge I have with this is creating a single view for the List and create. Each attempt I have made ended up in data type error. What do I do?

Also check your controller to ensure you are not passing Roles.ToList() to the CreateRole view. You can do this:

  [HttpGet]
    public ActionResult CreateRole()
    {
        var roles = from ur in db.roles
                    orderby ur.RoleName
                    select ur;
        ViewBag.Listroles = roles.ToList();
        return View();
    }

where db is your DbContext.

And your view should look like this:

  @{

      if(ViewBag.Listroles != null){
      foreach (var roles in ViewBag.Listroles)
        {
            <tr>

                <td>@roles.RoleName</td>
                <td>
                      @Html.ActionLink("Edit", "EditRoles", new { id=roles.RoleId }) |
                      @Html.ActionLink("Details", "Details", new { id=roles.RoleId }) |
                      @Html.ActionLink("Delete", "Delete", new { id=roles.RoleId })
                 </td>
            </tr>
        }

      }

    }

Let me know if my answer helps.

Answer 1:

In Order to hide some fields(as asked in Comments section) in @Html.EditorForModel() you have to use :

[ScaffoldColumn(false)] attribute

Ex :-

 [Key]
 [ScaffoldColumn(false)]
 public string RoleId {get;set;}

Answer 2:

and creating and showing list on the same view :

Model :

public class Roles
{
 [Key]
 public string RoleId {get;set;}
 public string RoleName {get;set;}
 public List<Roles> Roleslist { get;set; }  //Take a list in Model as shown
}

View :

 <div id="mainwrapper">

 @using (Html.BeginForm("// Action Name //", "// Controller Name //", FormMethod.Post, new { @id = "form1" }))
  {  

   @Html.TextBoxFor(m => m.RoleName)
   <input type="submit" value="Save"/>

  }
  <div id="RolesList">
   @if(Model!=null)
    {
      if(Model.Roleslist!=null)
      {
       foreach(var item in Model.Roleslist) //Just Populate Roleslist with values on controller side
       {
       //here item will have your values of RoleId and RoleName 
       }
      }
    }
  </div>

  </div>
