            {
                var model = new ResourceModel();
                model.RoleId = Convert.ToInt16(ds.Tables[0].Rows[i]["GroupId"]);
                model.RoleName = ds.Tables[0].Rows[i]["EmplopyeeRole"].ToString();

        conn.Close();
        return roles;
    }

this is my model

              public class ResourceModel
{
    public static List<ResourceModel> GetList { get; set; }
    public Int16 EmployeeId { get; set; }
    public string EmployeeName { get; set; }
    public string EmployeeEmailId { get; set;}
    public string GroupName { get; set; }
    public string EmployeePassword { get; set; }

    public static List<SelectListItem> GetRoles { get; set; }
    public int RoleId { get; set; }
    public string RoleName { get; set; }      

}

this is my aspxPage

    <%:Html.DropDownList("RoleName")%>

when i put a breakpoint and see that i have the data in GetRoles Method..can any one tell me where am i doing wrong

Answer 1

I guess the problem is you have a property in the model with the name RoleName and also you have it in the ViewBag.

So when you use <%:Html.DropDownList("RoleName")%> there is a kind of confusion.

I would suggest change ViewBag.RoleName into something like ViewBag.Roles and then try,

<%:Html.DropDownList("Roles")%>
