Remarks
Warning
Call the SelectAll method only when the SelectionMode property is set to Multiple or Extended. If you call SelectAll when the SelectionMode is Single or None, an exception is thrown.
Starting in Windows 10, you can use the SelectRange and DeselectRange methods with the SelectedRanges property to make selections using ranges of indexes. This is a more efficient way to describe item selection than using SelectedItems, which requires the actual item object to be created for each selected item. To select all items using index ranges, use SelectRange.
