To allow an easy customization of what columns to show in a grid by the user, an often used user interface is a list holding the available columns and allowing the user to drag & drop from the grid the columns that should be hidden or drag columns that should be displayed from the list to the grid. To achieve this functionality, a component is offered that integrate much of this functionality: TAdvGridHeaderList. The TAdvGridHeaderList is a listbox-style control that holds indexes of available (hidden) columns. By means of drag & drop from the column header to the list and vice versa, it is possible to define what columns to show or not show in the grid.
