I have a ASP.NET MVC 4 project with EF
I have a table with Parteners. This table has 2 types of parteners : agents(part_type=1) and clients(part_type=2).
In an Create view I have the first DropDownList that shows all my agents, a
button and the second DDL that shows all my clients that correspond to the selected agent.
Q1 : What
button shoud I use ? , , @Html.ActionLink() ?
Create.cshtml
<div class="editor-field">
@Html.DropDownList("idagenti", ViewData["idagenti"] as List<SelectListItem>, String.Empty)
</div>
@*a button*@
<div class="editor-label">
@Html.LabelFor(model => model.id_parten, "Client")
</div>
<div class="editor-field">
@Html.DropDownList("id_parten", String.Empty)
@Html.ValidationMessageFor(model => model.id_parten)
</div>
OrdersController.cs
public ActionResult Create(int? id) // id is the selected agent
{
var agqry = db.partener.Where(p => p.part_type == 1).Where(p => p.activ == true);
var cltqry = db.partener.Where(p => p.part_type == 2).Where(p => p.activ == true);
List<SelectListItem> idagenti = new List<SelectListItem>();
foreach (partener ag in agqry)
{
idagenti.Add(new SelectListItem { Text = ag.den_parten, Value = ag.id_parten.ToString() });
}
if (id != null)
{
cltqry = cltqry.Where(p => p.par_parten == id);
}
ViewData["idagenti"] = idagenti;
ViewBag.id_parten = new SelectList(cltqry, "id_parten", "den_parten");//
}
Q: How can I pass the selected agent id from the first DDL to my controller ?
