View Models in asp.net core

Dear all although its a very simple question and I guess it would be stright but I am facing issue so I am asking on that platform , I am having view model like below

public class AllModels

{

public class student{get;set;}

public class Grades{Get;set;}

public class Marks{get;set;}

}

ignore the typos if there are any, the issue is I have a view in which I am giving it this model and I only need to use Marks model but on model binding i am giving it complete viewmodel

@model Allmodels etc

Now I like to fire validation of only marks model but when i am saving the records it fire the validation of other two models grades and students as well how to prevent it should I bind my view with only MArks model but I cannot do that as I am using viewModel and on listing i need these other models too and my same view is used for creation as well as for listing.

try this way

public IActionResult Save(AllModels model)
{
    // Validate only the Marks model
    if (TryValidateModel(model.Marks))
    {
        // Proceed with saving the Marks data
    }
    else
    {
        // Return the view with validation errors
        return View(model);
    }

    return RedirectToAction("Index");
}

TryValidateModel() is a built-in method provided by the ASP.NET MVC framework. It is used in controllers to validate a specific model or a part of a model against its data annotations and validation attributes.
