asp.net mvc - why model posted to action Display in view? -

There are 2 verbs with the same name. (AddNewUser) One of them works with HttpGet and the second HTTP post. [HTTPGet] Add Public Activity AddNewUser () {User User = Utilities. Session Provider. GETCurrentUser (); If (user.ID_User == 0) Return Direct ("Apps.kosarfci.ir"); RoleType role = (RoleType) RoleDeterminer.RoleDeterminate (); If (Role! = RoleType.Center) {Return Redirect ToAction ("Ban"); } See Return ("Venue User"); } [Http post] Public Action Result AddNewUser (VMNewUser InModel) {User User = Utilities. Session provider GETCurrentUser (); If (user.ID_User == 0) redirect return ("Apps.kosarfci.ir"); RoleType role = (RoleType) RoleDeterminer.RoleDeterminate (); If (Role! = RoleType.Center) {Return Redirect ToAction ("Ban"); } IUserBL Center UsherBel = New Center User BL (); InModel.User.UserName = InModell.User.NationalCode; InModel.User.Password = InModell.User.PersonalCode; Confirm of BULLBL = CenterUsbLl Edusor (inmoded user); _msgList.Add (New Message () {MsgType = Message Type. Success, MsgContent = Message Provider. GetMessage (MessageContent.Submit_Success_NewUser)}); ViewBag.Message = _msgList; See Return ("Venue User"); }

AddNewUser (), return a form with the input entry and then the form submitted to AddNewUser (VMNewUser InModel). But after this, a form filling with the post model is displayed. I hope that a form with a blank input entry display because I do not send a pre-filled model (VMNewUser) in the scene?

 The main reason to send back the model of the population is to stop the user from stopping If there is an error in processing server-side, then refilling the form. It tells the client what field has failed and if any special error message should be displayed.  
 It is recommended that if this request is  is  successful, you will redirect the user to a new page. In your case, you can send the user back in the  AddNewUser  operation that will present the user with an empty form. for example.  
  Redirect Return ("AddNewUser");
