No, there's no functionality in the grid for this. You could code it yourself, of course, but the grid doesn't have this sort of undo capability built-in.

I want to be able to undo the changes of  cell. I realize there is a undo cell call you can make, but it does not track all the changes to a cell throughout a entire session. For instance, I change the text 'Bill' to 'Billie' and then to 'Billy' without leaving the cell; so the changes were not committed, if I then perform an undo on this text the value of the cell is put back to 'Bill' the original value. What I would want to happen is that if I hit undo, the text is changed back to 'Billie' and if I the perform the undo action again the text then changes back to 'Bill'. It doesn't seem like the undo functionality supports this capability correct?
