Everytime I encounter a situation which requires Parent/Child relationships I toy with the idea of using a grid and allow the user to view and maintain. Simple relationships I find somewhat doable but when it becomes more complicated with picklists and various other controls in each of the columns it seems to become a nightmare.

I generally end up just allowing the user to access the child through an entirely new form using a filter or something. It works fine and is infinitely less complicated.

I hear of others that seem to just pop the controls into each column of the grid as simply as putting them on a form and move on. No problem.

Am I missing something.
