Database1Entities db = new Database1Entities();
public ActionResult Index()
{
return View();
}
public ActionResult details()
{
var myParts = (from p in db.emps
join d in db.depts on p.Eid equals d.Eid
select new
{
name =p.name,
address = p.address,
number=d.number,
sub=d.sub
}).ToList();
return View(myParts);
}
}
}
My index page what should I give in model if I give the class name or table name if I give class name then I have two class the which class i give in above model
here this Index page code:
#model IEnumerable<two2.Models.mass>
#{
ViewBag.Title = " Deaprtment name ";
}
<h2>Index</h2>
#{
ViewBag.Title = "Department";
}
<table>
<tr>
<th>
#Html.DisplayNameFor(model => model.name)
</th>
<th>
#Html.DisplayNameFor (model => model.address)
</th>
<th>
#Html.DisplayNameFor (model => model.sub)
</th>
<th>
#Html.DisplayNameFor (model => model.mark)
</th>
<th></th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.name)
</td>
<td>
#Html.DisplayFor(modelItem => item.address)
</td>
<td>
#Html.DisplayFor(modelItem => item.sub)
</td>
<td>
#Html.DisplayFor(modelItem => item.mark)
</td>
</tr>
}
</table>
and my view page
in index page it is showing object not found
and in foreach statement it is showing error
#model two2.Models.mass
#{
ViewBag.Title = "deatils";
}
#using (#Html.BeginForm())
{
#Html.LabelFor(model => model.name)
#Html.TextBoxFor(model => model.name)
<br /><br />
#Html.LabelFor(model => model.address)
#Html.PasswordFor(model => model.address)
<br /><br />
<br /><br />
#Html.LabelFor(model => model.sub)

<br /><br />
<br /><br />

#Html.PasswordFor(model => model.mark)
<br /><br />
<button>Login</button>
}
I don't know what should I use such that my be class name or table name and how to display on view

Answer 1

You should use same class name in Action also which is used in View like:
public ActionResult details()
{
var myParts = (from p in db.emps
join d in db.depts on p.Eid equals d.Eid
select two2.Models.mass
{
Eid = p.Eid,
name = p.name,
address = p.address,
number = d.number,
mark = d.mark, // <- you need to pass mark as it is used in View
sub = d.sub
}).ToList();
return View(myParts);
}
If you are using in View:
#model IEnumerable<two2.Models.mass>
Class two2.Models.mass is one type of ViewModel and it should contain only those fields which are needed in View:
namespace two2.Models
{
public class mass
{
public int Eid { get; set; }
public string name { get; set; }
public string address { get; set; }
public int number { get; set; }
public string sub { get; set; }
public int mark { get; set; }
}
}
