Hi @Harun Ergün,

You provided a lot of code, but due to naming issues, we can only guess from the code.

Your update button is Güncelle and the update method is DepartmanGetir. DepartmanGetir is the HttpGET update method, and DepartnanGuncelle is the HttpPost update method?

I'm guessing you're having a naming issue, you need to change DepartnanGuncelle to DepartmanGetir.

Regarding the 404 issue, have you defined the cshtml page file of DepartmentmanDetay? and return the view in the controller?public ActionResult DepartmentmanDetay(){return View();}

I suggest you can study the documentation:
