TempData['value'] and ViewBag.value are updated in the controller, but remain same in the view

Question

Hi!

Using $.ajax, I update variables in TempData or in ViewBag without reloading the page (View).

But when the result of success: function (result) {} is returned in the View, the alert shows that the data has not changed.

As far as I understand, I definitely have to reload the page from the return View() controller? But I don't want to reload it.

Is there any way to change a variable in the View without reloading the page?

Thanks!

Answer 1

TempData and ViewBag are designed to pass data from the controller to the View. It is not possible to update TempData or ViewBag without making a trip to the server.

Is there any way to change a variable in the View without reloading the page?

I'm sure there is a way to solve the current programming problem if you explain the use case and share code that illustrates the issue.
