Data Annotation Validation not working in ASP.NET

I Have a form inside a Partial view that is rendered inside a tab on a tab control that looks like this:

@model USARAFSyncMVC.Areas.Event.Models.EventFullScaffoldModel

@using (Ajax.BeginForm("SaveMainEventDetails", "Event", new { area = "Event" },
    new AjaxOptions { UpdateTargetId = "FormWrapper", OnComplete = "SetSuccessLabel", InsertionMode = InsertionMode.Replace },
    new { method = "post" }))
{
    @Html.Hidden("eventType", "1", new { id = "eventType" })
    <div id="FormWrapper">
      <hr />
      <table border="0">
        <tr>
          <td>Title</td>
          <td>@Html.TextBoxFor(model => model.Title, new { style = "width:300px" })
            @Html.ValidationMessageFor(model => model.Title)</td>

        </tr>
        <tr>
          <td>OPR</td>
          <td> @Html.EditorFor(model => model.OPRID)</td>

        </tr>
        <tr>
          <td>Organization</td>
          <td> @Html.EditorFor(model => model.DomainID)</td>

        </tr>
        <tr>
          <td>POC</td>
          <td> @Html.EditorFor(model => model.POC)</td>

        </tr>
        <tr>
          <td>Location</td>

          <td>
            @Html.EditorFor(model => model.LocationID)
          </td>

        </tr>
        <tr>
          <td>Dates</td>
          <td>
            <table>
              <tr>
                <th>@Html.LabelFor(m => m.StartDate)</th>
                <th> @Html.LabelFor(m => m.EndDate)</th>
              </tr>
              <tr>
                <td> @Html.EditorFor(m => m.StartDate)</td>
                <td>@Html.EditorFor(m => m.EndDate)</td>
              </tr>

            </table>

            <table id="DeployRedeployDiv">
              <tr>
                <th>Deploy</th>
                <th>ReDeploy</th>
              </tr>
              <tr>
                <td> @Html.EditorFor(m => m.EstimatedDeployDate)</td>
                <td>@Html.EditorFor(m => m.EstimatedReDeployDate)</td>
              </tr>

            </table>

          </td>
        </tr>
        <tr>
          <td>OSRs</td>
          <td>
            @(Html.Telerik()
                  .PanelBar()
                  .Name("PanelBar")
                  .HtmlAttributes(new { style = "width:300px;" })
                  .Items(o => o.Add().Text("Click").Content(@<text> 

                @Html.CheckBoxList("OprList",
                    x => x.OprList,
                    x => x.OPRID,
                    x => x.AltTitle,
                    x => x.EventOSRs, Position.Vertical)</text>).Expanded(false)))
          </td>
        </tr>
        <tr>
          <td>Purpose</td>
          <td> @Html.TextBoxFor(model => model.Why, new { style = "width: 400px; height:200px" })</td>
        </tr>
        <tr>
          <td>Background</td>
          <td> @Html.TextBoxFor(model => model.What, new { style = "width: 400px; height:200px" })</td>
        </tr>
        <tr>
          <td>Viewable</td>
          <td> @Html.CheckBoxFor(model => model.Viewable)</td>
        </tr>

      </table>
      <div>
        <input class="t-button" type="submit" name="button" value="Save" />

      </div>

    </div>

}

Here is the Controller:

    [HttpPost]
    public ActionResult SaveMainEventDetails(EventFullScaffoldModel model, string[] OprList, string eventType, string cbLoc, string cbOpr, string cbOrg)
    {
        if (OprList != null)
        {
            model.EventOSRs = miscRepository.GetOprsList().ToModel().Where(o => OprList.Contains(o.OPRID.ToString())).ToList();
        }

        model.Type = int.Parse(eventType);
        model.LocationID = cbLoc;
        model.OPRID = int.Parse(cbOpr);
        model.DomainID = int.Parse(cbOrg);
        eventRepository.Insert(model.ToDto());
        return View();
    }

Here is the Model:

   public partial class EventFullScaffoldModel

        public IList<StrategicObjectiveModel> StrategicList { get; set; }

        public IList<OrgModel> OrgsList { get; set; }
    }

The Model NEVER get validated and runs straight through the transaction on the controller. Why is this not working?

回答1:

I suggest first to check whether you have included the necessary javascript files for unobtrusive validation in the right order and that will make the validation happen successfully at the client-side.

Regarding the server side validation as other told basically you have to save the model to the database by explicitly checking ModelState.IsValid. Since you are making an AJAX call I may suggest you to return the model state errors as JSON.

So in the OnFailure method of the AjaxOptions you can parse the JSON and display the errors as a summary in a div.

Basically you can follow this pattern.

[HttpPost]
public JsonResult SaveMainEventDetails(..)
{
  if(ModelState.IsValid)
  {
    .. save to database

    return Json(new{ success = true });
  }

  var errorDict =  ModelState..
  return Json(new { success = false, errors = errorDict });
}

回答2:

You need to explicitly check whether ModelState.IsValid in the action, and return to the edit view if it isn't.
If you show the edit view for an invalid model, MVC will automatically display error messages through the Validate helpers.

回答3:

This should shed some light: What is ModelState.IsValid valid for in ASP.NET MVC in NerdDinner?

Basically you have to trigger model validation by using ModelState.IsValid

回答4:

Add @{ Html.EnableClientValidation(); } in View

回答5:

Ok the problem was the Telerik Script Registrar was not referencing the proper JQuery. Now it is working. I was referencing the JQuery library directly, also the validation scripts. On the Telerik script Registrar, it is already a part of the default group , re-referencing them as I was doing, caused it to freak out for some reason. Only add references to scripts not apart of the original default group. For more info on that, one needs to read the online documentation for this MVC extension.
