I'm trying to do something like that :
user are able to select multiple cells at the grid then by edditing one cell all selected cell should automaticly change value (all cells has the same type of values).
I already wrote some custom CellSelectionModel and I have problem with changing value of selected cells.
I tried to change value directly at the model
but then selection dissapear and also I dont have dirtyCell marker (this little red triangle).
//after iterate all slected cells and chenge values:
Do you have any idea how to solve this problem, maybe already exists some solution for multiple cell edditing which I didnt find.
