How to change multiple cells in different rows at once in the grid?

Hello,
I want to select multiple cells in different rows - but in one column-, and inject a certain text (provided by a text box, or combo-box) into them.
I think a workaround is to get row range from another text box or something, but that's not very user friendly I think.
Thanks in advance.

Hi, I afraid that is not possible.
The only thing I did is to select and automatically begin editing the cell in the next row after hitting enter in the cell of the row before.
With regards, Fred

Thank you for reply.
so I  do the next plan then :D
