Class: TEgDBGridEx
property OnSortChange: TNotifyEvent;Fired after a column title click changes SortSelectedField
and/or SortDirection
- not fired if the click landed on a column that cannot be sorted, or
re-selected the same field and direction it already had.
TEgDBGridEx only tracks and displays the sort state; use
this event to actually reorder the dataset (for example, by assigning
IndexFieldNames or re-executing a query with a new
ORDER BY).
