Description
- Warning: Subclasses of TGridModel may not trigger OnGetValue.
Occurs when the grid, using this grid model, needs to retrieve a value from an external repository to use as the content of one of the cells in the grid.
Write an OnGetValue event handler to take specific actions when you retrieve a value from an external repository to use as the content of one of the cells in a grid using this grid model. OnGetValue event handler keeps the TCustomGrid.OnGetValue event handler. DoGetValue calls OnGetValue event handler.
