Question

i am getting a problem while populating data inside the dropdown…
I guess since i am using a partial view that is why it is creating problem.
Here’s my code:

public ActionResult Register()
{
    var course = from Course c in Enum.GetValues(typeof(Course))
                     select new { ID = c, Name = c.ToString() };
     ViewData["course"] = new SelectList(course, "ID", "Name");
     return view();
}

 public enum Course
{
    [Display(Name = "Basic Level", ShortName = "Basic")]
    Basic = 1,

    [Display(Name = "Intermidiate Level")]
    Intermidiate = 2,

    [Display(Name = "Advance Level")]
    Advance = 3
}

This is my Main view:

<table style="margin-top: 10px">
<tr>
    <td valign="top">
        @{Html.RenderPartial("LogOnPartial");}
    </td>
    <td width="20px">
    </td>
    <td align="left">
        @{Html.RenderPartial("CreatePartial");}
    </td>
</tr>

I have written this in my partial view(CreatePartial):

<td>
       @Html.DropDownList("course");
</td>

Please help me

This should work. I am unable to reproduce the problem.

Model:

public enum Course
{
    [Display(Name = "Basic Level", ShortName = "Basic")]
    Basic = 1,

    [Display(Name = "Intermidiate Level")]
    Intermidiate = 2,

    [Display(Name = "Advance Level")]
    Advance = 3
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var course = from Course c in Enum.GetValues(typeof(Course))
                     select new { ID = c, Name = c.ToString() };
        ViewData["course"] = new SelectList(course, "ID", "Name");
        return View();
    }
}

Index.cshtml view:

@{Html.RenderPartial("CreatePartial");}

CreatePartial.cshtml partial:

@Html.DropDownList("course")

I suspect that this is not working after you submit the form, not when it is initially loaded. And this might happen because you probably forgot to repopulate the ViewData["course"] in your [HttpPost] action and yet tried to redisplay the same view. If you want to redisplay the same view make sure that you fill the ViewData["course"] the same way you did in your GET action that was used to initially render the page.

Another thing to watch out is that you don’t have some other ViewData["course"] value that is conflicting.
