This setting determines whether the Column is visible in the online grid.
Typically, if you add a column to a grid, you want it to be visible. However, a non-visible Column can be useful in a situation where you want to use that column's field to sort or group the grid results, but not actually show that particular column in the online grid.
Check the Visible checkbox if you want the Column to be visible in EPConnect.
Uncheck the Visible checkbox if you do not want the Column to be visible in EPConnect.
