In my e-commerce site, I have a search page where the user can search for products by giving department, product type etc. and I display the result in a gridview in the same page itself. I have given a more details link in my datagrid which will take the user to details.aspx where the user can view the image and more details about product. I have a back button to come back button in the details page to come back the search page and view the other products in the result gridview. But, when the user comes back to the page, the grid will be empty. I want the search result to remain in the page. I am using object datasource. Can anyone help me?
