I put the code in the Init of the grid after doing a DODEFAULT(), is that okay?

That should work. FWIW, what I tend to do with my classes is have a "Set" method that is called from the class's Init(). SO, for my grid classes, I always have a method called SetGrid that is called from the Init() and my base form class has a template method called SetForm that is called from the Init, and so on. So, in my case, I would just put that line of code to my SetGrid method along with any other code required to setup the grid, like hightlighting the current row, for example.
