Thanks for your response

But Sir i have not written my own code for ajax,
Simply i used Ajax Control like DropShadow etc after installing the Ajax toolkit. But after using this my site is loaded very slow.

Check how large your ViewState is getting. (View Source and check the content of the hidden field containing the ViewState data.)

If you for example use a grid that has 10000 rows but only display 10 rows at a time, only 10 items are rendered in the html code for the contol, but all 10000 rows end up in the ViewState.

As guffa said, have you checked your view state size ?

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.

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.
