The CExtGridWnd class implements the CExtGridDataProvider::IDataProviderEvents interface (i.e. the CExtGridWnd class is derived from the CExtGridDataProvider::IDataProviderEvents class). The CExtGridDataProvider::IDataProviderEvents::OnDataProviderSortEnter() virtual method is invoked before grid data sorting. The CExtGridDataProvider::IDataProviderEvents::OnDataProviderSortLeave() virtual method is invoked after grid data sorting. The CExtGridDataProvider::IDataProviderEvents::OnDataProviderSwapSeries() virtual method is invoked during grid data sorting when two rows are columns become swapped. The CExtGridWnd::OnDataProviderSwapSeries() method is overridden implementation of the CExtGridDataProvider::IDataProviderEvents::OnDataProviderSwapSeries() virtual method. The CExtGridWnd::OnDataProviderSwapSeries() method modifies grid selection on the fly during re-sorting of grid rows or columns. As result, all the grid cells which were selected before sorting are staying selected after sorting.
