Class: TEgFireGrid
property OnTitleClick: TEgFireGridColumnEvent;
TEgFireGridColumnEvent = procedure(Sender: TObject; Column: TEgFireGridColumn) of object;Occurs when a column’s title is clicked or tapped, before the sort
changes; Column is the title’s column. A click on the
title’s icon fires OnTitleImageClick
instead, and the right button OnTitleRightClick.
Dragging a title to move or resize its column is not a click.
After the handler, the column’s sort direction changes (see OnSortChange).
The grid’s handler runs first, then the column’s own event of the same
name.
