Class: TEgFireGridColumn
property OnBeforeDrawCell: TEgFireGridBeforeDrawCellEvent;The column’s own OnBeforeDrawCell:
it occurs for the same things, with the same parameters, but only for
this column, right after the grid’s OnBeforeDrawCell
handler (if any). It receives Text as the grid’s handler
left it. Sender is the grid. See the grid’s event for when
it occurs and what the parameters mean.
Assigning one handler to the grid’s event serves every column; the column’s event suits a behaviour that belongs to one column, and travels with it when the column is copied or moved.
