Row-level buffering is near impossible to use correctly in grid because record become automatically updated as soon as grid is refreshed. Column.Refresh will cause auto-update too.

As about Valid event of grid, it is fired when grid lose focus, as far as know, so probably it can cause no conflicts but just will be called twice - once from control (your manual call) and once from grid (automatic call as event). From the OOP point of view better make a custom method. Direct call of event (like button.Click) should be avoided with exception of special situations.
