See more:

C#

[HttpPost]
public ActionResult Create(Users user) {
    if (ModelState.IsValid) {
        db.Users.Add(user);
        db.SaveChanges();
        return RedirectToAction("Index");
    }
    return View(user);
}

ModelState.IsValid is always false.
so it just return view and new record is not getting added.

What I have tried:

C#

[HttpPost]
public ActionResult Create(Users user) {
    if (ModelState.IsValid) {
        db.Users.Add(user);
        db.SaveChanges();
        return RedirectToAction("Index");
    }
    return View(user);
}

ModelState.IsValid is always false.
so it just return view and new record is not getting added.

Solution 1

You probably have submitted an invalid POST that is detected by some validation checks which you did not included in your question. The view should provide an error message in such cases.

A good description can be found at What is the ModelState? - ASP.NET MVC Demystified[^]-

It tough to help you find out what going on with a few line of codes. Basically, during the post, one or more of the model property is failing the validation. For instance, phone number, you might have had specified required validation attributes but never provide the information during the post.

Here is a link can give you some idea on how to debug the error.
