>In the AfterRowColChange of a grid, is there a way of determining if the Row or Column changed? I could do it by tracking RECNO() against a memvar or custom property but I was wondering if there is an easier built in way?

Nope. Most (including me) have subclassed the grid, added a property to store the current RecNo() which is executed in the BeforeRowColChange method. Then in the AfterRowColChange method we compare the RecNo() to the value in the new grid property. On previous threads, most say they do not use ActiveGridRow value to compare against because performance declines as table size [RecCount()] grows.

I have also added a custom method to my grid subclass that is (by default) always called by AfterRowColChange so I have an alternative to placing code when I use the grid. This custom method is called regardless of whether the row changed or not.
