But essentially, I am trying to create a grid which allows the developer to "lock" a number of columns starting from the leftmost column and "scroll" through the rest of the columns. If you have used MS Project or MS Excel, it is similar in nature to ID or Row column.

Do the locked columns have to be invisible, or merely locked so that cannot be accessed. The second would probably be easier to implement. I would assume that the effect at which you are aiming would be similar to locked rows or columns in excel or access where the lock rows and columns visible but cannot receive focus.

How close am I?
