How get List<~> fron View to Controller MVC [duplicate] - asp.net-mvc

Question

This question already has answers here:
Post an HTML Table to ADO.NET DataTable
(2 answers)
Closed 6 years ago.
I have three related tables
Tables
In the table "SelectedMaterial" need to enter the values in the column "CountMaterial" (initially there null)
Values
For this in controller I have POST and GET methods
public ActionResult EditCountOfMaterial(int id)
{
var selectedmaterial = db.SelectedMaterials.Where(m => m.CardId == id).ToList();
return View(selectedmaterial);
}
[HttpPost]
public ActionResult EditCountOfMaterial(List<SelectedMaterial> material)
{
//material = db.SelectedMaterials.Where(m => m.CardId == 3).ToList();
for (int i = 0; i < material.Count; i++)
{
//material[i] = db.SelectedMaterials.Where(m => m.CardId == 3).First();
db.Entry(material[i]).State = EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
I also have a view
#model IEnumerable<AccountingPlusProject.Models.SelectedMaterial>
#{
ViewBag.Title = "EditCountOfMaterial";
}
<h2>EditCountOfMaterial</h2>
#using (Html.BeginForm())
{
foreach (var item in Model)
{
#item.ReferenceMaterial.NameMaterial
<div class="form-group">
#Html.LabelFor(model => item.CountMaterial, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => item.CountMaterial, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => item.CountMaterial, "", new { #class = "text-danger" })
</div>
</div>
}
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
}
But from the view comes null values. How to pass list from View with a value?

Answer 1

Something like Below. The Posted back values have to be in array form.
#using (Html.BeginForm())
{
foreach (var item in Model)
{
var count= 0;
#item.ReferenceMaterial.NameMaterial
<div class="form-group">
#Html.LabelFor(model => item.CountMaterial, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => item.CountMaterial, new { htmlAttributes = new { #class = "form-control", #name="SelectedMaterial[" + count.ToString() + "].CountMaterial"} })
#Html.ValidationMessageFor(model => item.CountMaterial, "", new { #class = "text-danger" })
</div>
</div>
count+=1;
}
}
