Hello all, I'm looking for some information on how to implement a "Loading..." or "One Moment Please" page while a time-consuming database query returns. I have posted it in here to, hopefully, get an asp.net solution. I apologize for making this post, but it's one of those things that I just can't think of a good google query to get results back on. Forgive me, but I need some biological brain power. Links to written materials on the topic would be much appreciated. thank you
-Mike

I'd try and make the bottleneck to be the bandwidth then hard disk I/O but never the processors, so I wouldnt attempt to solve this one that way. But if you do, possibly you could call a response.flush before querying and send a status bar back, also just warn the user when they click the button and use a "if IsClientConnected" before displaying the results as they might of gone somewhere else.

There are a few Articles I know about that cover this topic, with sample code and explanations. I am just going to paste the links here and hope the moderator will allow them. Design Patterns- Asynchronous Wait State Pattern in ASP.NET by Lyn Robison

Solution you have seen on the web is as follows. It isn't widely documented. Have a hidden z-layer with "waiting" message and activate that as part of some javascript associated with the submit button. Works like this: action page
click button
z-layer brought to front: "wait..."
intensive query activated
when query has finished results will be displayed Hope this helps. Green2K.
