This is more of a question about possibilities since I've not used datagrids beyond displaying SQL/PHP data in columns. I've already seen that the columns can be indivdually colored, so I suspect that many other properties can be changed as well.
Can the text items in a datagrid respond to mouse events much like the TextArea and other text controls? Can they have tooltips? PopUps? Also, can the text be formatted like html text?
Or is the datagrid a good match for displaying "records" but not what I want to do?
You have to use item renderers for the datagrid columns.So you can display the data in whichever form you want and then you can show tooltips and other things that you want for the individual renderers.
