One of the problems with incorporating AJAX on a web page is when your doing partial postbacks you need to communicate to the user that the save button they’ve just clicked has actually done something. Without those whole screen refreshes the updates can happen so quickly that you do get the danger that the user doesn’t even know something has happened. Or the alternative scenario is that something will take a while but there’s no on screen indication that the page is actually doing something, so the user is just sat there wondering.

Most people get around these problems with a little AJAX update image, I’m sure you’ve seen them, little progress bars, or rotating images. They just tell they user, hold on I’m just processing something. It’s a great way to give some response back to the user. Now this article isn’t going to explain how to implement those in AJAX, if your writing an ASP.Net site, there’s plenty of examples for that online.

I just wanted to share a great little resource I found for creating those animated gif images in the first place. The site lets you choose an image type. Balls or progress bars of varoius sizes are available, you can choose a foreground and background colour. Once you choose your options, your given your perfect little progress gif, to just save and use.

The site is called http://www.ajaxload.info/

Take a look, it’s pretty neat.
