>>No way to post what I have. There is a form class, a custom class, a target form, a target grid, etc. No way for anyone to look at it systemically without having the entire application. Oh well. I got the active row stuff to work at least. Would have been nice to be able to move the mouse over a record in the grid and popup my information form.

For what works, I'm using something different where I locate my X,Y coordinate, use the RelativeRow and some calculations to determine if I'm over the currently selected row.

What I would like to really do is have my form popup when it is over any row, selected or not, but I'm having a hard time getting that to work. That is using MouseMove, but doesn't work. I would like it to work like my other one as it just calls a method in my custom class when the mouse is over the area of the selected row, but for a row that is not selected, the problem becomes more complex. And it was complex enough for me to get the first type working.
