Populating ASP.NET MVC DropDownList - asp.net-mvc

Question

OK, I've been Googling for hours and trying everything and can't get anything to work. I am learning MVC using Sharp Architecture and have generated some basic forms for creating Client objects. I want to fill the state drop down list with a list of US states and let the user pick from that list. I am able to populate the list and get the value back (to save the client) but when I go to edit the client, the client's current state is not selected. I have set the selected value in the SelectList:
<li>
<label for="Client_StateProvince">StateProvince:</label>
<div>
<%= Html.DropDownListFor(c=>c.Client.StateProvince, new SelectList(Model.StateProvinces, "id", "Name", Model.Client.StateProvince), "-- Select State --")%>
</div>
<%= Html.ValidationMessage("Client.StateProvince")%>
</li>
This does not seem to be good enough. What am I missing?

Answer 1

<%= Html.DropDownListFor(c => c.Client.StateProvince.Id,
new SelectList(Model.StateProvinces,
"id",
"Name",
Model.Client.StateProvince),
"-- Select State --")%>
This does it.
Hope this helps someone else.

Worked perfectly for me thanx! I used it to set a parent relation on a subcategory:
<%= Html.DropDownListFor(
model => model.Category.ParentId,
new SelectList(Model.Categories,
"CategoryId",
"Name",
Model.Categories.Where(x => x.CategoryId == Model.Category.ParentId).Single()))%>

I did it this way. Works well.
Controller
IFarmModelInterface service2 = new FarmModelRepository();
ViewData["Farms"] = new SelectList(service2.GetFarmNames(), "id", "FarmName", "XenApp");
View
<%: Html.DropDownListFor(m => m.Farm, (ViewData["Farms"] as SelectList)) %>

public ActionResult AllUsers()
{
List<Users> users = userRep.GetUsers();
var listUsers = (from u in users.AsEnumerable()
select new SelectListItem
{
Text = u.UserName,
Value = u.UserId.ToString(),
Selected = (u.UserId==6)
}).AsEnumerable();
ViewBag.ListItems = listUsers;
//ViewBag.SelectedItem = 2;
return View();
}
In AllUsers.cshtml
<p>#Html.DropDownList("ListItems")</p>

Answer 5

<%= Html.DropDownListFor(c => c.Client.StateProvince, new SelectList(Model.StateProvinces, "Id", "Name")) %>
and override ToString() for StateProvince to return Id, i.e.:
return Id.ToString();
This works but is not a perfect solution...

This is View - MVC Controller
#Html.DropDownListFor(m => m.Entity, new ABC.Models.DropDownPopulate().MyMethod, new { #class = "form-control input-inline input-medium" })
MyMethod Get Data List Bind With Dropdown Using SelectListItems
public List<SelectListItem> MyMethod
{
get
{
List<SelectListItem> dropdownList = new List<SelectListItem>();
var items = new DropDown_Bl().GetAll();
foreach (var item in items)
{
SelectListItem dropdownItem = new SelectListItem();
dropdownItem.Value = item.RnID.ToString();
dropdownItem.Text = item.Description;
dropdownList.Add(dropdownItem);
}
dropdownList.Insert(0, new SelectListItem() { Text = "Please Select", Value = "", Selected = true });
return dropdownList;
}
}
GetAll Method In Dropdown_Bl - Used to get data as list from database
public List<My_Table> GetAll()
{
var Items = _Context.MyRepository.GetMany(q => q.Area == "ASD").ToList();
return Items ;
}

public ActionResult AllUsers() {
List<Users> users = userRep.GetUsers();
var listUsers = (from u in users.AsEnumerable()
select new SelectListItem
{
Text = u.UserName,
Value = u.UserId.ToString(),
Selected = (u.UserId==6)
}).AsEnumerable();
// ViewBag.ListItems = listUsers;
ViewData["tempEmpList"]=listUsers;
return View(); }
Fill Dropdown
#Html.DropDownList("SelectedEmployee", new SelectList((IEnumerable) ViewData["tempEmpList"], "Id", "Name"))
