pass selected gridview row to another gridview on another page

Yes, as SAKryukov states this is the best option. I think what you need to do is in your gridview create a hyperlink column with the navigation property to your new page. Your binding should also add the data item id in the querystring of the hyperlink.

i.e. NavigationTarget="yourwebpage.aspx?dataId='<%# eval("dataItemId")%>'" Once you do this you can load your data again but only use that which matches the id in the query string????
