Q. I am trying to use TrueGrid in callback mode and getting all kinds of problems. The Help says that CheckRows is always called before Fetch - I set breakpoints and see that it does not get called at all sometimes. And why don't Refresh, RefreshColumn, and RefreshRow cause the Fetch event to be executed?
A. CheckRows is only called before Fetch on navigation. It used to check whether or not more data should be fetched. If you do a .Refresh, a .RefreshRow or .RefreshColumn it will not call the CheckRows, however it will always call a Fetch. The exception to this is if you are in debug mode stepping through the code. In this case the Fetch will not always work correctly.
