The RSS that you have mentioned is about some definations.

However the above code is to read the XML and display same on the page.

But if you want your code to display the updated pricing, then the rss xml must be updated after some interval of time.

If you can do the same, only then report will display the updated values

Hi
The above link is not providing any rss.
If the same is rss then the link should be giving some xml file.

The link is accepting some query string arguments, reading and displaying the same on scree.

You cannot do any thing with this.
Search for RSS for the same

I want to redirect to other web page. based on the click of ok button ,i used script of message box by using
ClientScript.RegisterStartupScript();
means after clicking ok button it must redirect to another page.

but if i put response.redirect() after the ClientScript.RegisterStartupScript() code. it automatically redirects to other page without displaying my message box, how to solve this problem.

pls give the code.

thanks in adv,

Why dont you use the Client itself to do the redirection instead of coming back to the server and doing Response.Redirect.
In short you need to write a Javascript function which will execute on click of OK button.

function RedirectAfterMessage()
{
   var message = "do you wanna redirect?";
   if(confirm(message))
      window.location = "www.google.com";
}
