Both Bill Lam's code and mine do essentially the same thing, just in different ways. Bill's is more concise and cleaner for a simple application but separating the updating of the grid in its own verb is perhaps tidier once the grids and/or application become more complex.
I don't think the features they use are undocumented or even unrepresented in the example code, rather that you found them illuminating because they addressed the specific problem that you had. The following example uses a lot of the same techniques as my code. http://www.jsoftware.com/jwiki/Grid/Examples#Gridsinatabbeddialog > From: Donald Pittenger > Ric, > > The items that seemed new to me were as follows.
