Is it possible to make an abstract class that handles a pre-render of the page showing what you want to show (image/gif) while the user waits for the page to load?
How about managing every object-load in the page?
For example, I have a large image with a lot of stuff in it. But I know it’s size long before I load it. I could put a darkscreen on the location I’ll be placing the image with a loading animated gif within it.
What I want to avoid is the user to see the slow upside down load of every single image.
Could it be possible to see some code examples of how is it done? Do you use Silverlight for this?
This isn’t a server-side thing.
ASP.net receives a request and sends a response from and to the browser respectively.
No server-side action can manipulate client-side DOM.
If you want to do that you need to use JavaScript and DHTML approaches, because this way you’ll be able to render an entire page and leave some areas in a “loading” state while some resource is being loaded.
