Variety of approaches to preserve an input focus in a virtualized dataset is described. An application initiates operations to preserve an input focus in a virtualized dataset by presenting an initial page of items from a large dataset in a visible area. A spacer associated with a non-rendered page of items from the large dataset is rendered in a virtual area of the application. Next, an initial focus position is assigned to the initial page of items. Furthermore, the initial page of items is stored in a focus page index in an association with the initial focus position.
