Implementing events
NxVirtualCellSource6 includes several events that can be implemented in order to provide important information back to the grid.
In order to show any data, OnGetCell
and OnGetRowCount
events need to be implemented.
OnGetRowCount
event require number of rows as a result. That value will be used for specifying Max value for the vertical scroll bar and used for internal drawing loop.
Example
pas
Result := FProductsRepository.ProductCount;
