datagrid problems

[brain2cpu]

I saw a lot of datagrid messages but still remain a few questions for me: 1. there is a simple way to know if the grid was edited or not (= any cell changed, deleted, added or not) 2. I want a grid that is not readonly but allows just update or update and delete but no insert, ... 3. want to scroll down: when the grid is show the last lines be visible 4. a kind of alternate color: change rows background upon a cell value (have more records for a day and I want to have rows for same day in same color, changing background for the next day) Thanks
