MVC Html.BeginForm and page reload

I used to develop some applications in C#/Winforms and now I'm trying to learn web development with MVC.

It's a lot of new concepts (JS,Ajax,ASP.net, etc...), so please be tolerent...

I have read a lot and began to work and try, but there is a point that I still don't understand.

For exemple, I want to insert datas in a database via a Form, just insert, nothing else.

The method to insert is in the controller.

The evident method is to use Html helper @Html.BeginForm. At this step I'm not able to do that without reloading the whole page.

Due to the fact that I didn't find any clear answer, could you please help me.

1-Is it possible with @Html.BeginForm to do nothing after posting form in order to insert in database (maybe with a specific return type of the action in the controller) or Ajax.BeginForm is the unique solution ?

2-Same to update a part of a page, is ajax the unique solution ?

Many thanks.

I have create one form in asp.net core with post data using ajax It's working Create Partial View

@model Department

<h2>Create</h2>
<script src="~/lib/jquery/dist/jquery.js"></script>
<script src="~/lib/jquery-validation/dist/jquery.validate.js"></script>
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>
<div class="form-horizontal">
    <form asp-action="Create" role="form" asp-controller="Department" asp-antiforgery="true"
          data-ajax-success="Bindgrid"
          data-ajax="true"
          data-ajax-method="POST">
        <div class="form-group">
            <label class="control-label" asp-for="DepartmentName"></label>
            <input class="form-control" type="text" asp-for="DepartmentName" />
            <span asp-validation-for="DepartmentName" class="text-danger"></span>
        </div>
        <input class="btn btn-primary" type="submit" value="Save" />
    </form>
</div>

Controller logic

[ValidateAntiForgeryToken()]
        [HttpPost]
        public JsonResult Create(Department department)
        {
            if (ModelState.IsValid)
            {
                Context.Department.Add(department);
                Context.SaveChanges();
            }
            return Json(department);
        }
