Razor Page: ModalView wołane z linku a nie z buttona

Witam.
Mam problem z otagowaniem linka tak, żeby wołał ModalPartialView. Obecnie wywołuję okno edycyjne tak:

                                            <button type="button" class="btn btn-sm btn-info text-white mb-0 mt-0 ml-1 mr-1 p-1"
                                                    data-toggle="ajax-modal"
                                                    title="Edycja nazwy"
                                                    data-url="@Url.Page("Index","StagePartial")&[email protected]">
                                                <i class="fas fa-edit"></i>
                                            </button>

Chciałbym użyć zamiast buttona klikalnego wiersza w tabeli. Niestety poniższe nie działa :(

                                        <a href="#editstage" data-toggle="modal" data-target="#editstage">@stage.Title</a>

pomoże ktoś coś?

Poniżej obszerniejszy fragment kodu strony razorowej i widoku modalnego

Jest dobrze pamiętam jak to działa to Twój modal musisz wyrenderować na stronie. Obecnie zwracasz widok bez komponentu modal, a co za tym idzie to kliknięcie linka odnosi do czegoś co nie istnieje.

Spróbuj do tego użyć partial view.

To właśnie jest PartialView i z buttona działa jak trzeba ale nie wiem jak ostylować tag "a href=..." żeby robił to samo co z buttona
