True and False value does not change-CodePudding

I have a code like this:

public IActionResult Urgent(TodoTable t)
{
    var Task = db.TodoTables.SingleOrDefault(i => i.Id == t.Id);
    Task!.Urgent = t.Urgent; // If the value is True it will change to False and if False it will change to True.
    db.SaveChanges();
    return RedirectToAction("Index");
}

And Index.cshtml:

<a  href="/TodoTables/Urgent/@item.Id">@(item.Urgent ? "Unurgent" : "Urgent")</a>

If the Urgent value in the database is True, it will be False, and if False, it will be True. But I could not do this on the Controller side. Only True becomes False, then does not become True again.

How can I do that?

Can you try replacing your code like this?

Task.Urgent = !Task.Urgent;
