However I have a page that does not use ajax, it uses a postback to reload the page. However the load is rather data intensive and it takes a few seconds. During this time the user can still click on the page. I want to turn the cursor to "waiting" so the user does not try to click on the page.
For example I have a couple of dropdowns that cause postback. I make a selection and the page loads for 3 seconds. While it loads I would like the cursor to turn to waiting so the user does not try to make a selection on a second dropdown until the page reloads.
