>I am creating a form that includes a grid to edit shift assignment for employees. Employees are in rows and dates are in columns, with summary info in left columns and in the last two rows.
>
>User should be able to change desired dates at will, therefore changing the number of columns in grid. Also columns that refer to dates should have a horizontal scroller associated with it and rows that refer to employees need a vertical scroller.
>
>This may be doable with a class of four synchronized grids, with only one grid showing the vertical scroll bar and another one showing the horizontal scroll bar, yet programmatically keeping all grids in synch. Has anyone done something like this and is willing to share :) See attached design.

You can use this for starters: Why would anyone want an automated total grid?.
