Grids - Refresh & change record

[StephanM]

I found the answer to question 2.
You assign an event to the grid's first column's OnClick event (not OnAsyncClick) and locate the new record there.

Still looking for a way to refresh the grid with changed data.
I tried the following but no success.
grid->Invalidate() ;
grid->Repaint() ;
grid->RepaintControl() ;
grid->Refresh() ;
