No problem, below i will be pasting three things, the first section will contain my objects that I am binding to the grid.  There are two tiers, the top tier is the parent band and the second tier is the child band.  The second thing i will post is my "LoadScheduleGrid" function which binds the object to the grid and the final section will be the actual grid in my .aspx page.
