Hi john,

Thanks for the reply.I Have found one thing.All my modules images use the images folder under the root directory.i have found the menu item images have ../../../ added to them by checking it using firebug.so i have hardcoded the url from http://localhost/sample4.7/images/image.jpg in order to test wether it was the problem.But the same error is being repeated.No other image paths has ...please see if you can help me.

Thanks,

Hi Sandeep,
Why don't you create a grid viewcontrol just for outputing to the document without anyof the dynamic control or links in it. 
So you'd generate a grind view.
Databind it to the same source as your other grid view and then render it as you did before.
