AJAX in itself doesn't make the page slow. We are using AJAX on our web site, and the servers are handling up to 200 requests per second.
However, you can easily go wrong if you don't really know what's happening below the surface, creating something that uses much more resources than it would have to.

That's not something that I would say is typical use for AJAX, or something that you would need AJAX at all to accomplish. What controls are you using for that?

As you said that
<b"creating something="" that="" uses="" much="" more="" resources="" than="" it="" would="" have="" to.="">
Could you give me some idea about that what type of resources can be caused of slow process and which thing i shoule keep in mind to create fast access because i m newbie to asp.net and its my first site.
Thanks a lot

The bottle neck is usually the transmission between the server and the browser, so usually when a page is slow it's because there is a lot of data send from the server to the browser.
Check the page properties in the browser to see how large the html document itself is.
In Firefox you can use the plugin Firebug to monitor exactly what's loaded to the browser, how large the files are, and how long time it takes.
Despite everything, the person most likely to be fooling you next is yourself.

This is very complex. You need to write a HTTP handler to serve the images, if you cannot write them onto your file system first. Then you can create elements in your page that call this file handler and get back the byte data. It's far easier if you can write the images to the HDD first. Then it's just an img tag.

Adding to CG's post, you can also create an ASPX page which reads the database image and return it to the response. Set this page as src in an img tag. You need to set the ContentType also before you write it to response.

I would go with what CG said, but if you can't writing an ASPX page that serves an image is how you have to do it. It won't be hard to find some sample code that does both.

thx Chris.
Can we do it through Javascript?Or any other way you can suggest?
The requirement is to trigger emails to the Administrator through a wepApp if there is any problem with the printer attatched to the machine in which that Wepapp is browsed.

ASP.NET doesn't have access to the client machine like that. You might be able to with an ActiveX control...

There is no way for this. ASP.NET or Javascript is not built for this. Javascript works inside the browser and executed by the browser. So you don't have permission to access devices like printer.

Try using Meadco ScriptX. It also has a free edition. That should limited interaction with the printer.

What makes you think the AccordionClass DOES have a property called AccordionExtender ? What code is causing this error ?

OK - I guess you need to read up on how the ASP.NET AJAX library is configured, you obviously have something wrong there.

I'm sorry, I don't use it. I prefer to write my own AJAX code. But, there are samples on the Microsoft site. You should download the samples and if they build, work out how their code is different to yours. Also, one possibility is that you named your page after the control, and that's confusing the compiler. Did you ?

Sounds like you're really lost. I recommend buying a basic book on ASP.NET and reading it. I can't even make sense of your questions.
