Hello i have a problem with one surface controller who doesn't have access to the "CurrentPage". When i try to access this im getting this error "Cannot find the Umbraco route definition in the route values". The controller is invoked by Javascript with the culture "Culture" property. Please if any have experience with these Surface controllers, i should appreciate any help. If more information is needed please ask for a picture of the controller itself.

Compare the working

BeginUmbracoForm

request with your AJAX request. Sounds like the path, querystring or POST data is wrong/insufficient. But in 9+ you need to register your Umbraco routes in a way you didn't need to in 7/8. If you look into the documentation on registering surface controller routes it could be there.

You might be missing the anti forgery token (or other things!) https://docs.umbraco.com/umbraco-cms/reference/routing/surface-controllers#preventing-cross-site-request-forgery-xsrf-csrf-attacks Have a look at the docs and see where yours differs!

Thank you, can u give me an example where to register this route? I saw the documentation but I'm a little bit lost.

If it's a normal surface controller, the URL is

/umbraco/surface/{controllername}/{action}/{id}

Yep I'm calling the controller with this route like you mention, but by Ajax call. The idea is to post a formal and if there is an error to render the error without refresh the whole page

There is no Current Page if you just invoke a surface controller. There is only the surface controller. The concept of a "current page" for a surface controller is magic injected by Umbraco. If I just POST to your controller from nowhere, what would the current page be? There was a page that you invoked the Umbraco form from, and that page is probably being passed to Umbraco and picked up by the surface controller when you

BeginUmbracoForm

. Unless there is a

BeginUmbracoAjaxForm

, you probably have to pass a page ID in the form ("current page ID"), and use

UmbracoContext

in the controller, but not

CurrentPage

. So sort of "brew your own" BeginUmbracoForm but for AJAX. (Didn't know people still said AJAX 🙂 )

You should be able to do something like below, change your submit button into a normal button and give it an id. In your javascript post the form like this

js
$(document).on("click","#signin-btn", function (e) {  
    e.preventDefault();
    e.stopPropagation();
    var form = $("#submitsigninform");

    $.ajax({
        url: "/umbraco/surface/membershipsurface/submitsigninform",
        type: "POST",
        data: form.serialize(),
        beforeSend: function (xhr) {
            xhr.setRequestHeader("RequestVerificationToken",
                $('#submitsigninform input:hidden[name="__RequestVerificationToken"]').val());
        },
        error: function (xhr,  status, error) {
            console.log(xhr.responseText);
        }
    });
});

In your surface controller your method should look like

cs
        [HttpPost]
        [ValidateUmbracoFormRouteString]
        [IgnoreAntiforgeryToken]
        public IActionResult SubmitSigninPage( PortalSigninViewModel model)
        {
            var test = UmbracoContext.PublishedRequest.PublishedContent;

            if (ModelState.IsValid)
            {
                ...

                //something was wrong so add an error
                ModelState.AddModelError("SigninError", result);

                return CurrentUmbracoPage();
            }

            return CurrentUmbracoPage();
        }

Thanks a lot i think that is the solution what im looking for.
