This example demonstrates the three selection modes in DataViews: single, multiple, and none.
The default behavior when clicking or touching a row is to select it and when you move to another row, the original is deselected and the new one is selected.
This is called single selection. You can set two other behaviors, multiple and none. In multiple selection,
rows are added to the selection as they are clicked or touched. With the none option, rows are never selected.
To set the selection mode, use the selectionMode property and set the value to single, multiple, or none. Try changing the selectionMode with the drop down menus above the grid.
