Abstract: One or more visible user interface controls from a cache can be displayed. The user interface controls can also include one or more virtualized controls and one or more partially visible controls. In response to an indication to move in a dimension, one or more displays of visible user interface control(s) can be changed, and a control can be virtualized in the cache. Also, in response to the indication to move, one or more of the user interface controls in the cache can be recycled by performing population (i.e., populating the control) with data from outside the subset of data items in the data set. Additionally, an indication to change the number of controls in the data set can be received, and in response, the number of controls in the cache can be changed.
