Description

Hi,

There is an issue with MultiSelectCells functionality of CellNav module. I can select multiple cells using CTRL + cell selection, however after scrolling the grid (up or down) the multi-selection gets cleared and only the first cell from the collection remains highlighted.

It can be reproduced in the CellNav tutorial: http://ui-grid.info/docs/#/tutorial/202_cellnav

  1. Select multiple cells using CTRL + selection
  2. Scroll the grid up/down
  3. Observe the selections disappearing.

Contributor guide

Research direction
Inspect the CellNav module's code to understand how multi selection state is stored and cleared on scroll. Look for scroll event handlers and trace where the selection array is reset, likely in the grid cell rendering logic.
