Class: TEgColumn
property OnTitleImageClick: TEgDBGridTitleImageClick;Column-level counterpart of TEgDBGridEx.OnTitleImageClick
- same signature and same trigger (a click landing on this column’s
title image rather than elsewhere in the title cell). Both fire when
assigned, grid-wide handler first, so this column’s own handler can
react to or override whatever the grid-wide handler already decided. See
TEgDBGridTitleImageClick.
Requires TitleImageIndex
to actually be set on this column.
