Editing single entry and show multiple in ASP.NET MVC - asp.net-core

Question

I am very new to this and I am trying to show multiple entries to show and have a single button for each entry to edit them. I thought it would be really easy but For some reason I am not getting the clicked entity. Is there way of getting modified entity without running javascript?
Any help will be appreciated. I couldn't find any example code that does this. There are many examples that returns all the entries but not the single element.
Here is my entity class Resource:
public class Resource
{
[Required]
public string title { get; set; }
[Required]
public int value { get; set; }
[Key]
[Required]
public int id { get; set; }
}
On the controller side I have:
[HttpGet]
public IActionResult Index()
{
return View(resources);
}
[HttpPost]
public IActionResult Index(Resource resource)
{
return View(resource);
}
Here is the View and EditorTemplates
#model learningMVC.Models.Resource[]
#{
ViewData["Title"] = "index";
}
<h1>index</h1>
<fieldset>
#Html.EditorFor(x => x);
</fieldset>
#addTagHelper "*, Microsoft.AspNetCore.Mvc.TagHelpers"
#model learningMVC.Models.Resource
<div>
First Name:<br />
<form asp-action="Index" asp-controller="Home">
<input asp-for="id" class="form-controller" />
<input asp-for="value" class="form-controller" />
<input asp-for="title" class="form-controller" />
<input type="submit" value="Save" class="btn btn-primary" id="btnSubmit_#Model.id" />
</form>
</div>

In your case, you should use particalview instead of editfor, you can see my demo below.
_ResourcesPartical.cshtml:
#model Resource
<div>
<form method="post" asp-action="Index">
First Name:<br />
<input asp-for="id" class="form-controller" />
<input asp-for="value" class="form-controller" />
<input asp-for="title" class="form-controller" />
<input type="submit" value="save" />
</form>
</div>
Your Index view:
#model List<Resource>
#foreach(var m in Model)
{
#await Html.PartialAsync("_ResourcesPartical", m)
}
Controller:
[HttpGet]
public IActionResult Index()
{
//here you get your data.below is my fake data.
var resources= new List<Resource>
{
new Resource
{
id = 1,
title = "aa",
value = 3
},
new Resource
{
id = 2,
title = "bb",
value = 4
}
};
return View(resources);
}
[HttpPost]
public IActionResult Index(Resource resource)
{
return RedirectToAction("Index");
}
Test result:
