Show Progress in a Web Form

[Guest]

I have seen this subject tossed around in this forum before. But in my case I
need a simple solution. I do NOT need to show progress in terms on percentage
complete. But rather I need to show a visual indicator to the user that a
process is running.

There are two scenarios where I need to show a busy indicator:

Scenario #: The first is when posting to the web server and waiting for a
response.

Scenario #2: When launching a new window and waiting for it to load.

In either case, there is a delay in waiting for SQL data to be read and
rendered into HTML content.

I have tried using a popup window with an animated GIF. It can be centered
on the screen easily. But it is a separate non-modal window and mechanisms
for closing it from a separate window are not so easy. I have tried to
implement this and ran into problems in the Scenario #2 above.

I have thought about an iframe in the same window also.

I welcome any ideas on this subject. Perhaps there is a simple solution I
have not yet tried.

Always best to deal with the source of the problem, in this case SQL. What
exactly is taking so long, before applying a band-aid solution?

Why not put the animated GIF in a web form Image control, position it
absolutely on the page and simply show it or hide it via the control's
"visible" property?

animated gifs generally will not run during a postback.

Sure they will. What are you talking about?

 

[bruce barker]

during postback, the broswer generally shuts down the background thread used
to animate the gif (you have cache it for it to even display - though this
is not reliable). this is why progress pages with an animated gif do a
refresh on a timer.

I have never heard of such a thing. This makes absolutely no sense
whatsoever. A postback causes the page to be re-generated and re-delivered
to the client. The browser does not know that it is receiving a postback.
If in the response to the client there is an HTML image tag that happens to
use an animated graphic as its source, the browser will render it.

I tried this for myself and it works just fine.

Yes, but put in a long running process in the same page as the gif. So
you're saying you can flush the response for the gif, and then 30 seconds
later, complete the response?
