razor: show editable list
// You need form tag in order for HttpPost. The trick is to either use for loop to generate
// correct Ids, or create Partial View.
// I like to use partial view, since it is a bit cleaner.
// For example
// ViewModel
public class SampleViewModel
{
public IList<IncidentListmodel> IncidentListmodel = new List<IncidentListmodel>();
}
// Model
public class IncidentListmodel
{
public int Id { get; set; }
public string Name { get; set; }
public string Title { get; set; }
public string Note { get; set; }
}
// View
@model AspNetMvc.Models.SampleViewModel
@foreach (var item in Model.IncidentListmodel)
{
@Html.Partial("_UpdatePartial", item)
}
// Partial View (_UpdatePartial.cshtml)
@model AspNetMvc.Models.IncidentListmodel
@using (Html.BeginForm("Updateinc", "Home"))
{
@Html.HiddenFor(m => m.Id)
@Html.HiddenFor(m => m.Name)
@Html.DisplayFor(m => m.Name)
@Html.DisplayFor(m => m.Title)
@Html.TextAreaFor(m => m.Note, 2, 20, new { maxlength = 50 })
<button type="submit">Update</button>
}
// Controller
public class HomeController : Controller
{
public ActionResult Updateinc()
{
var model = new SampleViewModel
{
IncidentListmodel = new List<IncidentListmodel>
{
new IncidentListmodel {Id = 1, Name = "One", Note = "Sample text"},
new IncidentListmodel {Id = 2, Name = "Two"},
new IncidentListmodel {Id = 3, Name = "Three"},
}
};
return View(model);
}
[HttpPost]
public ActionResult Updateinc(IncidentListmodel viewModel)
{
// Rediret to different page.
return RedirectToAction("Index");
}
}
