Do you guys implement IListServer for the BOs and if not, can you point me in the right direction of how to implement this myself?  We are are generating a few really large datasets and it is taking a while to render them without having this implemented.  Thanks!

This logic will be entirely up to how you handle the code behind the custom property. Back to basics first, a BO.Sort uses the CurrentView.Sort property. So the sort is ultimately handled in the ADO.NET table behind the BO.



Depending on how you are sorting, then you can either force a column into the CurrentDataTable for sorting purposes, or if there is an IComparer option, you can do anything you want. This would allow you to pull the logic out of the standard BO sort. I don't have any first hand experience with the IListServer interface, but the IBindingList implementation may be a similar comparison in regards to the Sort implementation. In this case, in a BBS, we rely on the sort of the BO, not recreating an internal sort.



Don't know if any of this helps, but this isn't an easy to answer question because there are a lot of factors that can be involved.
