Data list modifications disappear when adding new rows
I have a data list that holds in the first columns some small icons (rich text) that are hidden. I want them to show according to the input of the user (for example if a user chooses to modify sth on that row, there should be shown the corresponding icon, if the user chooses to add sth another icon etc). However when I add a row at the data list the icons dissapear again. Do you have any ideas how this can be avoided?
Also, I try to modify cells (I want to add the current date and hour) through a pop-up. However when I try to change again the date and time, again through a popup, to a different row it changes the date and time on all rows.
Do you have any solutions to these?
