I'm running a server method from an Action. How can I display a Progress Bar while this method is running?
I'd recommend checking out this forum post for some sample code of displaying a progress bar from a client action. It's not possible to control the client directly through a server method, but it would be possible to rewrite your action to instead call a client method which calls your server method as done in the original question from the linked forum post.
