Some widget toolkits distinguish between a grid and a datagrid. If this is the case, the term datagrid refers specifically to a widget that can be linked to a database with little or no effort from the part of a programmer.
They are commonly used to display lists of files, such as the "Details" view in Windows XP file managers.
Grid views are sometimes referred to as spreadsheet widgets (or spreadsheet controls, with control being a common synonym for widget). This is due to grid views' visual and sometimes behavioral similarity to spreadsheet applications. However, though many grid views support editing of underlying data, they can't be used for arbitrary calculations. Spreadsheet widgets occur frequently in scientific applications such as PSPP or SPSS.
