MVC 3 C＃::提交表單後保留表單的值

我只是想在MVC3提交我的形式httppost方法後保留我的表單數據

我不想交任何地方後重定向，相同的形式，我想我的提交值回在各個領域

上

任何消化？

我在下面的方法

[AcceptVerbs(HttpVerbs.Post), ValidateInput(false)] 
    public ActionResult PostJobAction(FormCollection PostJobForm, HttpPostedFileBase uploadfile, JobsDetailModel objLocationModel) 
    { 
     bool blnSavedResume = false; 
     // JobsBusinessComponent objJobsBusinessComponent = new JobsBusinessComponent(); 
     JobsClient objJobsBusinessComponent = new JobsClient(); 
     UserModel objUserModel = null; 
     // byte[] bytArrayResume = null; 
     string strlogoImageName = string.Empty; 
     if (uploadfile != null) //if (uploadfile != null && uploadfile.ContentLength > 1024) 
     { 
      string UserFolderName = ConfigurationManager.AppSettings["LogoPath"].ToString() + objLocationModel.InstituteName.Trim(); 

      if (!Directory.Exists(UserFolderName)) 
      { 
       Directory.CreateDirectory(UserFolderName); 
      } 

      strlogoImageName = Guid.NewGuid().ToString() + "_" + uploadfile.FileName; 
      blnSavedResume = Utility.ResizeStream(Convert.ToInt16(ConfigurationManager.AppSettings["LogoSize"]), uploadfile.InputStream, UserFolderName + @"\" + strlogoImageName); 
      //using (MemoryStream ms = new MemoryStream()) 
      //{ 
      // var filePath = System.IO.Path.GetFileName(uploadfile.FileName); 
      // Image image = Utility.ScaleBySize(Image.FromFile(uploadfile.FileName, true), 200); 
      // uploadfile.InputStream.CopyTo(ms); 
      // bytArrayResume = ms.GetBuffer(); 
      //} 
      //// byte[] bytArrayResume = uploadfile.InputStream. 


      //blnSavedResume = objJobsBusinessComponent.SaveResumeOnDisk(UserFolderName, uploadfile.FileName, bytArrayResume); 
     } 
     if (blnSavedResume) 
     { 
      objUserModel = Utility.GetGuestUserData(); ; 
      //objLocationModel.StateID = objUserModel.StateID; 
      objLocationModel.CountryID = objUserModel.CountryID; 
      objLocationModel.LogoFileName = strlogoImageName; 
      objJobsBusinessComponent.PostJob(objLocationModel, 4); 
     } 
     TempData["Message"] = "Success"; 
     //return RedirectToAction("Index"); 
     if (ModelState.IsValid) 
     { 
      return View(objLocationModel); 
     } 
     else 
     { 
      // Dropdown selected values needs to be repopulated here , if there error in the model. 
      return View(objLocationModel); 
     } 
     // return View("~/Views/Employer/PostJob.cshtml"); 
    }

這是剃刀代碼做處理。建議我如果我做錯了，因爲我對MVC完全陌生。

您可以使用模型'objLocationModel'返回視圖，或者做一個ajax帖子。 –

只是返回視圖與填充模型;

return View(objLocationModel);

謝謝克里斯，但是，你能告訴我如何將這些值綁定到我的CSHTML文件？它給了我錯誤。 –

@DhavalMarthak向我們展示了您的模型的結構和您查看的標記，以便我們可以進一步提供幫助。您可以編輯您的問題並添加其他代碼。 –

我已經添加了一些代碼片段，你可以再次看看我的問題 –

 [HttpPost] 
     public ActionResult PostJobAction(FormCollection PostJobForm, HttpPostedFileBase uploadfile, JobsDetailModel objLocationModel) 
     { 
      if(ModelState.IsValid) 
      { 
       return View(objLocationModel); 
      } 
      else 
      { 
       // Dropdown selected values needs to be repopulated here , if there error in the model. 
       return View(objLocationModel); 
      } 
     }

我更新了我的問題，你會清楚我想要做什麼 –

你可以與我們分享剃鬚刀代碼，以及什麼控件獲取值以及什麼控制失去價值。 –

再次更新代碼，添加剃刀文件內容 –

好了，問題是，你有你的頁面上的幾個DropDownList的是來自ViewBags但這些ViewBags沒有在PostJobAction重建。讓我重申一下Hari Gillala所說的使用ViewBag並不好，至少不是那樣。

讓我們先解決您的問題，綁定到你的模型，當你與模型這樣的回報您的視圖將保留其值的任何控件：

[AcceptVerbs(HttpVerbs.Post), ValidateInput(false)] 
public ActionResult PostJobAction(FormCollection PostJobForm, HttpPostedFileBase uploadfile, JobsDetailModel objLocationModel) 
{ 
    return View(objLocationModel); 
}

接下來要做的事情是有值在下拉菜單中，所以你需要重新創建ViewBags：

[AcceptVerbs(HttpVerbs.Post), ValidateInput(false)] 
public ActionResult PostJobAction(FormCollection PostJobForm, HttpPostedFileBase uploadfile, JobsDetailModel objLocationModel) 
{ 
    // do this code after you are done doing your stuff 
    // you always need to do this since you want to have the same form whether there is an error or your operation is a success 
    ViewBag.JobTypeList = create_this_list(); 
    ViewBag.InstituteType = = create_this_list_also(); 
    return View(objLocationModel); 
}

但有做你現在正在做什麼更好的辦法，那就是創建一個包含一些屬性，包括您的清單模型：

// The Model 
public class JobActionFormModel { 
    public JobsDetailModel InputModel {get;set;} 
    public IEnumerable<JobType> JobTypes {get;set;} 
    public IEnumerable<InstituteType> InstituteTypes {get;set;} 
} 

// The way you build it 
[AcceptVerbs(HttpVerbs.Post), ValidateInput(false)] 
public ActionResult PostJobAction(FormCollection PostJobForm, HttpPostedFileBase uploadfile, JobsDetailModel objLocationModel) 
{ 
    var model = new JobActionFormModel { 
     InputModel = objLocationModel, 
     JobTypes = create_this_list(), 
     InstituteTypes = create_this_list_also(), 
    } 
    return View(objLocationModel); 
} 

// The way you consume it on your view 
<td width="319" height="30" align="left"> 
    @Html.DropDownListFor(x => x.InstituteType, new SelectList(Model.InstituteTypes, "Id", "Value", Model.InstituteType, new { @class="select" }) 
</td> 
// same goes for all your lists
