I can't give you a lot of help, but I'll give you what I know. Dynamics calls the lines for a grid (scrolling window) into Dexterity and manipulates it from there. It's not really exposed to us in VS Tools. You can set an event to fire when a key field is populated (for example: in the SOP Transaction Entry window, when the Item Number is populated), but I've had issues with that. In a 5 line window, the event fires 6 times. Grrr.
They say that they will expose the grid in version 10. We'll see. In the meantime, here is what I've been able to learn about the grid. The ones with just my name on them are conversations with $upport.

If you learn more, please come back and post it for the community. (That applies to any VS Tools topic) Thanks!
