How to retrieve value from DropDownListFor html helper in ASP>NET MVC2?
- by Eedoh
Hello
I know there was few similar questions here about DropDownListFor, but neither helped me...
I use Entity Framework as ORM in my project. There's EF model called "Stete". Stete has Foreign on EF model called "Drustva"
Now I'm trying to make a form for editing the data, for Stete model. I managed to display everything, including Stete.Drustva.Naziv property, but I can't get this last property in my handler method [HttpPost]. It always return 0, no matter what I select in drop down list.
Here's the code:
DrustvaController:
public static IEnumerable<SelectListItem> DrustvaToSelectListItemsById(this KnjigaStetnikaEntities pEntities, int Id)
{
IEnumerable<Drustva> drustva = (from d in pEntities.Drustva
select d).ToList();
return drustva.OrderBy(drustvo => drustvo.Naziv).Select(drustvo => new SelectListItem
{
Text = drustvo.Naziv,
Value = drustvo.Id.ToString(),
Selected = (drustvo.Id == Id)? true : false
});
}
SteteController:
private IEnumerable<SelectListItem> privremenaListaDrustava(int Id)
{
using (var ctx = new KnjigaStetnikaEntities())
{
return ctx.DrustvaToSelectListItemsById(Id);
}
}
public ActionResult IzmijeniPodatkeStete(Int32 pBrojStete)
{
PretragaStetaModel psm = new PretragaStetaModel();
ViewData["drustva"] = privremenaListaDrustava(psm.VratiStetuPoBrojuStete(pBrojStete).Drustva.Id);
ViewData.Model = new Models.Stete();
return View("EditView", (Stete.Models.Stete)psm.GetSteta(pBrojStete));
}
EditView:
<div class="editor-label">
<%: Html.Label("Društvo") %>
</div>
<div class="editor-field">
<%: Html.DropDownListFor(m => m.Drustva.Naziv, ViewData["drustva"] as IEnumerable<SelectListItem>) %>
<%: Html.ValidationMessageFor(model => model.FKDrustvo) %>
</div>
I am sorry for not translating names of the objects into english, but they hardly have appropriate translation. If necessary, I can try creating similar example...
