How can we Pass Data From Partial Views To Parent View Controller Action methods

In .NET MVC you have a couple of options to pass values around. when going controller-to-controller, you can use the TempData[] collection for single hops. Only controllers can access this collection, and it is primarily useful for action redirects.

If you need to persist data for a use in a given session, you can use the Session[] collection to provide an application state per user, per session. All views and controllers can access this collection.

You can use the ViewData[] collection to pass elements into the view and assign them to variable containers (such as JavaScript variables) that are known by the Master view. You can then make any changes on the client side using JavaScript.
