Ajax Editing business errors not showing up

[Jatin]

Hi,
   I am trying to implement ajax editing (Popup mode) in Telerik Q2 grid. The Model is EntityFramework model which has data annotation for various property validation. After submitting the ajax edit form, if there are any errors related to the Model annotations, these errors show up correctly. However if I use ModelState.AddModelError() add business errors to model, these errors does not show in the grid ajax edit form. Is it possible to display business error message like the ones that are displayed when the TryUpdateModel() fails ?

Here is the simplified code that I am using

<!-- Model Editor Template -->

@Html.ValidationSummary()
    <div class="content">
        @{Html.RenderPartial("_UserEdit");}
    </div>


//Controller
[GridAction][HttpPost]

public ActionResult _UserUpdate(int id) {

    User user = userManager.FindUser(id);

    if (user != null) {

        if (TryUpdateModel(user)) {

            try {

                userManager.EditUser(user);

            }

            catch (Exception ex) {ModelState.AddModelError("RepositoryException",ex.Message);     //Does not show up

            }

        }

    }

    return View(new GridModel(userManager.GetQueryableUsers()));

}

That was a silly question. ValidationSummary cannot be used in ajax calls. So then how do we show custom errors in Ajax popup editing ?

Any response on this.  I am having the same issue.  Sometimes I need to display a field level error message in the pop up which works fine, however if I want to display any sort of error message using @Html.ValidationSummary()  those errors do not get displayed.  Using the code @Html.ValidationSummary does not display the individual field level error messages either. 

Thoughts?
