Dynamically turning inline edit inputs on/off based on drop down in first column.

[Tony]

I have a grid with three different "types" in it.

Type A = uses fields 1,2,3,4,5,6,7.
Type B = uses fields 1,2,3,6,7.
Type C = uses fields 2,3

We still require a rollup view with all the data in the table.

I have the grid showing the data; and using a drop down to determine the "type".  

I can read the value of the dropdown on change.

I can't, for the life of me, get the fields to turn off/on based on that selection.

Oh yes; forgot; this is a grid with the row made inline editable.  Please; any ideas?

Thanks.
Tony
