When paging is enabled for the RadListView control, the RadListView is aware only for the records displayed on the current page. Therefore to achieve your goal, you can loop through the items on the current page and see if there is the desired item. If not, then change the CurrentPageIndex of the RadListView and loop again through its items and so on, until you get to the proper page.
Another option is to find the desired record in the RadListView data source and calculate on which page it would appear in the RadListView. Then set the CurrentPageIndex and rebind it.
Give it a try and let me know if any questions arise.
All the best,
the Telerik team
