Disclosed herein is a system and method for selecting items or tiles when they are displayed using a virtualized display window. The system uses the row relative coordinates of each tile to determine whether those tiles were selected by the user. As the user scrolls or moves off of the originally displayed window, information related to the unrealized tiles that were once realized is stored so that selection of unrealized tiles is possible. Typically, the user will select tiles by indicating a starting point and drawing a rectangle to the desired ending point. Information related to the tiles that are intersected by the rectangle or enclosed in the rectangle are stored for use in the selection process in case those tiles are unrealized during the selection process. Once the tiles have been selected the user can perform operations on the selected tiles in a customary fashion.
