I would like to trim the string or remove whitespaces for the string entered in my textboxfor field called "VAREmail" in mvc. The html code used is

<div class="detailsRow">
           <div class="detailsLabel">
               @Html.LabelFor(m => m.VarEmail, Strings.VarEmail)
           </div>
               @Html.TextBoxFor(m => m.VarEmail, new { style = "width:50%" })
               @Html.ValidationMessageFor(m => m.VarEmail)

       </div>

The controller code triggered when same button is clicked is

[HttpPost]
       public ActionResult Edit(Supplier supplier)
       {

           if (!ModelState.IsValid)
           {
               supplier = GetSupplier(supplier.SsoId);

               return View("Edit", supplier);
           }

           ReviewerDto dto = googleReviewService.GetReviewerBySsoId(supplier.SsoId);

           dto.GoogleReviewEmail = supplier.EmailAddress;
           dto.MorpheusId = supplier.MorpheusId;
           dto.VarEmail = supplier.VarEmail;
           dto.SesameEmail = supplier.SesameEmail;
           dto.SesameFirstName = supplier.SesameFirstName;
           dto.SesamePassword = supplier.SesamePassword;
           dto.VettedReviewer = supplier.VettedReviewer;

           googleReviewService.UpdateReviewer(dto);

           supplier
               .ReviewerRates
               .ToList()
               .ForEach(rr => googleReviewService.SetReviewerRateActiveStatus(supplier.SsoId, rr.RateId, rr.Active));

           return RedirectToAction("List");
       }

the model used with some regular expression fro validation is

[StringLength(50)]
      [RegularExpression(@"^(?i)[A-Z0-9._%+-]+@[A-Z0-9]+.com", ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "ReviewerEditModel_InvalidEmailEntered")]
      [Display(ResourceType = typeof(Strings), Name = "VarEmail")]
      public string VarEmail { get; set; }
