Re: Please Wait Image Control

Tech-Archive recommends: Fix windows errors by optimizing your registry

Is it possible you could give me an example of the calling code. Can you
set multiple update panels to trigger when a page loads? I'm not sure how
to implement your suggestion.

TIA

Yes, it is tied to UpdatePanel. I assume you would use one for dynamic
image
fetching from your web service?

Doesn't the UpdateProgress control fire in reaction to an UpdatePanels
postback event?

The UpdatePanel wont be posting back as the code to get the image is set.

ASP.NET AJAX has support for both 'in progress' indication as well as
connecting to web services. For UpdateProgress see
http://ajax.asp.net/docs/tutorials/IntroductionUpdateProgress.aspx

For web service interaction from ASP.NET AJAX:

Hope this helps?

Hi,

I have a webservice that returns a byte[] for an image. I'd like to
disaplay an image while the webservice is being contacted and then
once
the
byte[] is available show that and remove the please wait image.

I was thinking of trying to use the CallBack mechanism but wondered if
AJAX
would be better suited.

I'd really just appreciate some ideas on how this could be acheived.
I'll
need to do this many times on a page hence why I want to make each
call
asychronous.

TIA
