  [MVC 4 WebApp] Passing id from view to ActionResult method.

  Jan 28, 2013 08:55 PM|LINK

  Hey,

  I have the following data model :

  public class Job
      {
          public int jobID { get; set; }
          public string description { get; set; }
          public string companyName { get; set; }
          public JobType jobType { get; set; }
      }
  
      public class JobType
      {
          public int jobTypeID { get; set; }
          public string typeName { get; set; }
          public List<Job> jobList { get; set; }
      }

  Now I want to write a ActionResult AddJob-Method, which created an job instance puts it in the jobs DB and adds it to the List<Job> of a JobType:

  The ActionResult methods:

    //
          // GET: /ManageJobs/CreateJobType
  
          public ActionResult AddJob(JobType jobtype)
          {
              ViewBag.JobTypeID = jobtype;
              return View();
          }
  
          //
          // POST: /ManageJobs/Create
  
          [HttpPost]
          public ActionResult AddJob(Job job, JobType jobtype)
          {
              if (ModelState.IsValid)
              {   
                  jobtype.jobList.Add(job);
                  db.Jobs.Add(job);
                  db.JobTypes.Add(jobtype);
                  db.SaveChanges();
                  return RedirectToAction("Index");
              }
  
              return View(job);
          }

  The AddJob View:

  @model GeliexMVC4App.Models.Job
  
  @{
      ViewBag.Title = "AddJob";
  }
  
  <h2>AddJob</h2>
  
  
  @using (Html.BeginForm()) {
      @Html.ValidationSummary(true)
  
      <fieldset>
          <legend>JobType</legend>
  
          <div class="editor-label">
              @Html.LabelFor(model => model.description)
          </div>
          <div class="editor-field">
              @Html.EditorFor(model => model.description)
              @Html.ValidationMessageFor(model => model.description)
          </div>
  
          <div class="editor-label">
              @Html.LabelFor(model => model.companyName)
          </div>
          <div class="editor-field">
              @Html.EditorFor(model => model.companyName)
              @Html.ValidationMessageFor(model => model.companyName)
          </div>
  
          <p>
              <input type="submit" value="Create Job Typ" />
          </p>
      </fieldset>
  }
  
  <div>
      @Html.ActionLink("Back to List", "Index")
  </div>
  
  @section Scripts {
      @Scripts.Render("~/bundles/jqueryval")
  }

  
  
  My first Q ist: How do I pass the jobtype instance from the view to the post-AddJob ActionResult?

  My 2nd Q : How Do I set the jobtype field of the new job in the view (as it must be the one which is save in the ViewBag)? Or do I have to set it in the post-ActionResult?

  In your view, withing your html form, jjust include a hidden field like below

  <input type="hidden" name="jobtype" value="@ViewBag.JobTypeID" />

  It will then get posted along with your form data when you post the form. The posted job type id will be bound to the second argument by the ModelBinder.
