Set the FlexGrid's selectionMode property to MultiRange to enable Excel-style multi-range selection.
Users will be able to select multiple ranges by ctrl-clicking and dragging on the grid.
The selectedRanges property gets an array containing CellRange objects that contain the currently selected ranges.
The sample shows how you can provide Excel-style dynamic data summaries for the current selection (regular or multi-range).
It also shows how you can export selected ranges to CSV files.
Note that clipboard and export commands only work for multi-range selections if all selected ranges refer to the same column range or to the same row range. (Excel also behaves this way.)
