Force a row to be changed

Is it possible to forcibly set a row , or cell, to think that it has changed so that the getChangedRows() will have that row in it?

getChangedRows tracks edit operations, and this is the only way to mark a row as changed
but you can use next direct update to mark some cell as update ( as result related row will be marked as updated, and included in list generated by getChangedRows() )

    grid.cells(i,j).cell.wasChanged=true;
