I have multiple gridviews that show when a user logs into the system and they take a few seconds (~15) to load. I would like to load a loading image to be displayed while the gridviews are loading. Once they have loaded, hide the image and show the gridviews. Each gridview will need to load independently, currently they are each in their own user control. I have used Matt Berseths method to do this but they all load at the same time which is very inefficient.
In a nut shell I need the page to load, fire the update progress control to load the associated gridview, then display the gridview when it is loaded. I really dont want to bog the system down with javascript so AJAX is prefered.
