It is complex; When I put in the Dynamic* for dColumn, I was testing on

Linux, that doesn't exhibit the screen flicker. On Windows though, it is

horrible. It's actually better than it was, but I need to rewrite how it

is handled. Perhaps I could try some Freeze/Thaw calls which would be

relatively easy though.

Please add a ticket to dabo, component 'ui', keywords 'dGrid flicker

dynamic'.

That's probably the best idea anyway. The Dynamic* properties of dColumn

are relative to the current row, so they are really meant for things

like BackColor, ForeColor, Font, etc.: things you want to look different

depending on the record it is representing. You probably don't want

Caption based on a particular row in the grid's dataset, but on

something external to that dataset.
