Question

I have created one page in MVC 3.0 Razor view.
Create.cshtml

@model LiveTest.Business.Models.QuestionsModel
@*<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>*@
@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)
    <table cellpadding="1" cellspacing="1" border="0">
        <tr>
            <td>@Html.LabelFor(model => model.TestID)
            </td>
            <td>
                @Html.DropDownListFor(model => model.TestID, (IEnumerable<SelectListItem>)ViewBag.ItemIDList)@Html.ValidationMessageFor(model => model.TestID)
            </td>
        </tr>
        <tr>
            <td>@Html.LabelFor(model => model.Question)
            </td>
            <td>@Html.EditorFor(model => model.Question)@Html.ValidationMessageFor(model => model.Question)
                @Html.HiddenFor(model => model.QuestionsID)
            </td>
        </tr>
        <tr>
            <td>@Html.LabelFor(model => model.IsRequired)
            </td>
            <td>@Html.CheckBoxFor(model => model.IsRequired)@Html.ValidationMessageFor(model => model.IsRequired)
            </td>
        </tr>
        <tr>
            <td> 
            </td>
            <td>
                <input type="submit" value="Submit" />
            </td>
        </tr>
    </table>
}

QuestionsController.cs

 public class QuestionsController : Controller
    {
        #region "Attributes"
        private IQuestionsService _questionsService;
        #endregion

        #region "Constructors"
        public QuestionsController()
            : this(new QuestionsService())
        {
        }
        public QuestionsController(IQuestionsService interviewTestsService)
        {
            _questionsService = interviewTestsService;
        }
        #endregion
        #region "Action Methods"
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult Create()
        {
            InterviewTestsService _interviewService = new InterviewTestsService();
            List<InterviewTestsModel> testlist = (List<InterviewTestsModel>)_interviewService.GetAll();
            ViewBag.ItemIDList = testlist.Select(i => new SelectListItem() { Value = i.TestID.ToString(), Text = i.Name });
            return View();
        }
        [HttpPost]
        public ActionResult Create(QuestionsModel questions)
        {
            if (ModelState.IsValid)
            {
                _questionsService.Add(questions);
                return RedirectToAction("Index");
            }
            InterviewTestsService _interviewService = new InterviewTestsService();
            List<InterviewTestsModel> testlist = (List<InterviewTestsModel>)_interviewService.GetAll();
            ViewBag.ItemIDList = testlist.Select(i => new SelectListItem() { Value = i.TestID.ToString(), Text = i.Name });
            return View(questions);
        }
        #endregion
    }

QuestionsModel.cs

public class QuestionsModel : IQuestionsModel
    {
        [ReadOnly(true)]
        public Guid QuestionsID { get; set; }

        [Required]
        [DisplayName("Question")]
        public string Question { get; set; }
        [DisplayName("Test ID")]
        public Guid TestID { get; set; }
        [DisplayName("Is Required")]
        public bool IsRequired { get; set; }
        [DisplayName("Created By")]
        public Guid CreatedBy { get; set; }
            }

Problem:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

If I am adding the above two lines in Create.cshtml page and then I press submit button then it will fire validation message “Question is required!” if I am entering value in *Question field and then press submit button my [HttpPost]Create Method never execute.*

If I remove the above two lines from page then press submit button then it will execute [HttpPost]Create Method and fire validation from server side if I am entering value in Question field then also [HttpPost]Create executed.

Please help me.

Answer 1

The QuestionsModel class includes a property CreatedBy which is not included in your View.

Try either adding CreatedBy as a hidden field, or (better yet) remove CreatedBy from the QuestionsModel class, since it is not an attribute which should be exposed in the view.

I suspect that this missing property is the cause of the problem.

UPDATE

I ran some tests on your code, and it was not the CreatedBy property. Rather, your problem is that you are not supplying a QuestionsID value, but you included a hidden field for QuestionsID on the form.

Because QuestionsID is a value type, by default, the DataAnnotationsModelValidatorProvider adds a Required validator to the QuestionsID field. Because the field did not have a ValidationMessage, you could not see the validation error.

You can override the behavior of the default DataAnnotationsModelValidatorProvider by following the instructions in my answer here.
