Using GirdDataBoundGrid, selecting a cell(click the cell), press Ctrl+C to copy the content, press the Arrow(up, down, left, right) to move to another cell, press Ctrl+V to paste the content...
the CurrentCellChanged event never occurs
This is by design.
When you paste text, CurrentCellChanged is not fired, but this.gridDataBoundGrid1.Model.PasteCellText is fired instead so you can catch the pasting into any cell, not just the currentcell. So, you will need to subscribe to this evenbt to catch a paste into a cell.
