How to show sort direction arrows in header of a virtual grid

[Administrator]

I''m implementing a virtual grid (as it will have to hold 10k+ rows) and I''m implementing the sorting by having pre-sorted indexes in my data model. How do I get the virtual grid to display an ascending or descending arrow in the header row?

Check out the Grid\samples\quickstart\GridControlSort sample. It displays a sort header in a gridcontrol. It handles the header in the SortCols method. Instead of calling grid.Data.SortbyColumn in that method, you could call your sort routine.
