Do you mean you cannot pass data to controller,because the model binding failed.It’s because your asp-for="item.xxx",so your passed data will be like this. 
If you want to bind the data,Here is a demo worked:
Controller:
[HttpGet] public ActionResult EditPersonnelModel() { EditViewModel e = new EditViewModel(); List<PersonnelModel> list = new List<PersonnelModel> { new PersonnelModel { id = 1, Email = "123@123", Nom = "n1", Prenom = "p1", Statut = "s1", Telephone = "123" }, new PersonnelModel { id = 2, Email = "1234@1234", Nom = "n2", Prenom = "p2", Statut = "s2", Telephone = "1234" } }; e.personnels = list; return View(e); } [HttpPost] [Route("id")] public ActionResult EditPers(PersonnelModel p) { EditViewModel e = new EditViewModel(); List<PersonnelModel> list = new List<PersonnelModel> { new PersonnelModel { id = 1, Email = "123@123", Nom = "n1", Prenom = "p1", Statut = "s1", Telephone = "123" }, new PersonnelModel { id = 2, Email = "1234@1234", Nom = "n2", Prenom = "p2", Statut = "s2", Telephone = "1234" } }; e.personnels = list; return View("EditPersonnelModel",e); } EditViewModel:
public class EditViewModel { public List<PersonnelModel> personnels { get; set; } } PersonnelModel:
public class PersonnelModel { public string Nom { get; set; } public string Prenom { get; set; } public string Email { get; set; } public string Telephone { get; set; } public string Statut { get; set; } public int id { get; set; } } View:
@model EditViewModel @{ ViewData["Title"] = "EditPersonnelModel"; } <h1>EditPersonnelModel</h1> @foreach (var item in Model.personnels) { <div class="col-md-4"> <form asp-action="EditPers" method="post" asp-route-id="@item.id"> <div asp-validation-summary="ModelOnly" class="text-danger"></div> <input type="hidden" asp-for="@item.id" name="id"> <div class="form-group"> <label asp-for="@item.Nom" class="control-label"></label> <input class="form-control" asp-for="@item.Nom" name="Nom"> </div> <div class="form-group"> <input class="form-control" asp-for="@item.Prenom" name="Prenom"> <span asp-validation-for="@item.Prenom" class="text-danger"></span> </div> <div class="form-group"> <input class="form-control" asp-for="@item.Email" name="Email"> <span asp-validation-for="@item.Email" class="text-danger"></span> </div> <div class="form-group"> <input class="form-control" asp-for="@item.Telephone" name="Telephone"> <span asp-validation-for="@item.Telephone" class="text-danger"></span> </div> <div class="form-group"> <input class="form-control" asp-for="@item.Statut" name="Statut"> <span asp-validation-for="@item.Statut" class="text-danger"></span> </div> <div class="form-group"> <input type="submit" value="save" class="btn btn-info text-white " /> </div> </form> </div>} Result:
