Class: TEgFireGridColumn
property OnColumnMoved: TEgFireGridColumnMovedEvent;The column’s own OnColumnMoved:
it occurs for the same things, with the same parameters, but only for
this column, right after the grid’s OnColumnMoved
handler (if any). It fires for the column that was moved.
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.
