progress bar in mvc

In my project, on a particular view I am having various ajax calls and during the access to the database and displaying the data, it`s taking a long time. I want to have some开发者_Python百科thing like a progress image pops up, that would be displaying till the data are displayed and making the view where the data would be displayed as a modal, such that the user can no more click on anything on that page. Can I have an idea or guide how can I achieve that? Is there the possiblilty of progress bar in MVC or any suggestion is welcomed, any example please.

It may be overkill if you've not already got jQuery and jQuery-UI on your site, it can be done by creating a modal dialog: http://jqueryui.com/demos/dialog/#modal
that contains a progress bar: http://jqueryui.com/demos/progressbar/

You can then poll the server for the progress and update the appearance of the progress bar.
