#Html.EditorFor required = "required" not working - html

Question

I want to validate #Html.EditorFor that it is required to input, but not working in asp.net mvc
<div class="form-group"> <label>First Name editor*</label>
#Html.EditorFor(x => x.Requester.FirstName, new { #class = "form-control", required = "required" })
#Html.ValidationMessageFor(m => m.Requester.FirstName)
</div>
sorry for my simple question because it is really frustating try to fix this issue
my controller code
[HttpPost]
public ActionResult Index(ViewModel.Ticket m)
{
try
{
using (DatabaseManager ctx = new DatabaseManager(true))
{
if (string.IsNullOrEmpty(m.TicketNo))
{
m.TicketNo = TicketNo.Create(User.Identity.Name, "TICKET");
}
Ticket obj = ViewModel.Ticket.ConvertToTicketBusiness(m);
obj.Requester = m.Requester.Email;
obj.TicketStatus = TicketStatus.Open.ToString();
obj.Escalation = User.Identity.Name;
obj.CreatedBy = User.Identity.Name;
obj.CreatedDate = DateTime.Now;
obj.UpdatedBy = obj.CreatedBy;
obj.UpdatedDate = obj.CreatedDate;
if (obj.IsValid)
{
obj = obj.Save();
}
Customer cust = ViewModel.Ticket.ConvertToCustomerBusiness(m.Requester);
if (string.IsNullOrEmpty(cust.CreatedBy))
{
cust.CreatedBy = User.Identity.Name;
cust.CreatedDate = DateTime.Now;
}
cust.UpdatedBy = User.Identity.Name;
cust.UpdatedDate = DateTime.Now;
if (cust.IsValid)
{
cust = cust.Save();
}
ctx.SaveChanges();
}
ViewBag.SuccessMsg = "Success";
}
catch (Exception ex)
{
ViewBag.ErrorMsg = ex.Message;
return View(m);
}
return RedirectToAction("Inbox");
}

Answer 1

Insert # Like: #required="required"

Answer 2

This is how it worked for me (ASP.NET MVC 5). Add
#data_val="true"
with
#required="required"
Final code:
#Html.EditorFor(model => model.FullName, new { htmlAttributes = new { #class = "form-control", #data_val="true", #required="required" } })
by adding , the form started to use jquery validator.

Answer 3

When you want to validate mandatory form input do not use EditorFor() if your MVC bellow 5.1, just using TextBoxFor() thank you
