Is it possible for me to show first the proj_no, then filename and then ID in the grid.


yes, with ColumnOrder column property.

But attention, at runtime VFP use a two column swap alghoritm.

ColumnIndex ColumnOrder  
 1              1
 2              2
 3              3
 4              4
 5              5

ActiveColumn = 4 is the ColumnOrder of the column where is the control with focus, and then it is Column4.

Now, change the position of Column4 to 2. For do this:
Set Column4.ColumnOrder = 2.

Now:
 1              1
 2              4
 3              3
 4              2
 5              5

ActiveColumn = 2 is the ColumnOrder of the column where is the control with focus, and then it is Column4.
