It would be very helpful to have an option in the Columns to Exclude section that would check/uncheck all columns.
For example if you only want to export two columns out of 50, check to exclude all columns first then uncheck the two columns you want.
It does. Right-click.
There is even a faster way to do this.....in the grid, before you choose Export Dataset....select across the columns that you want to export (assuming that they are next to each other), then in Export Dataset, you will have a rt-click option to export only selected columns.
Way cool! I'll tell the other developers here!
