I have a page with a partial macro RegisterModel and simple action to register new user. Basically based on this articles:

https://24days.in/umbraco-cms/2015/extending-membership/ https://24days.in/umbraco-cms/2014/dealing-with-members/

I want to return validation errors from ModelState to the page/ macro if user exists or any other validation or status error is returned.

How do I do it?

var model = new SupplierRegisterModel();

    using (Html.BeginUmbracoForm<MembersController>("MemberRegister"))
    {
        <fieldset>
            <legend></legend>

                @Html.ValidationSummary("model", true)
                <div class="form-group">
                    @Html.LabelFor(m => model.CompanyName)
                    @Html.TextBoxFor(m => model.CompanyName)
                    @Html.ValidationMessageFor(m => model.CompanyName)
                </div>
                <div class="form-group">
                    @Html.LabelFor(m => model.FirstName)
                    @Html.TextBoxFor(m => model.FirstName)
                    @Html.ValidationMessageFor(m => model.FirstName)
                </div>
            <div class="form-group">
                @Html.LabelFor(m => model.Surname)
                @Html.TextBoxFor(m => model.Surname)
                @Html.ValidationMessageFor(m => model.Surname)
            </div>
                <div class="form-group">
                    @Html.LabelFor(m => model.Email)
                    @Html.TextBoxFor(m => model.Email, new { @class = "text ui-widget-content ui-corner-all" })
                    @Html.ValidationMessageFor(m => model.Email)
                </div>
                <div class="form-group">
                    @Html.LabelFor(m => model.Password)
                    @Html.PasswordFor(m => model.Password)
                    @Html.ValidationMessageFor(m => model.Password)
                </div>

                @Html.HiddenFor(m => model.MemberTypeAlias)
                @Html.HiddenFor(m => model.RedirectUrl)
                @Html.HiddenFor(m => model.UsernameIsEmail)

                <div class="form-group">
                    <button type="submit" class="btn btn-default">Register as supplier</button>
                    @if (TempData["Status"] != null)
                    {
                        <p>
                            @TempData["Status"]
                        </p>
                    }
                </div>

        </fieldset>
    }

This:

return View()

cannot be done as the macro is embedded in a page.

This:

return PartialView()

will render just the partial content without the layout.

In addition partial cannot be strongly typed so I have no means to return the model into the partial to display ModelState errors.

With:

return RedirectToCurrentUmbracoUrl()

I can just reload the page with TempData.

I have no idea how to return errors into the ValidationSummary.

Any ideas how this things are handled with macro partials in umbraco 7?
