About GridColumn components
Grid columns can act like edit components, combo box components, or check box components. The default behavior for a grid column is the same as that of an edit component. If you specify a List Source for the column in the Component properties sheet, it behaves like a combo box. If you set the Check Box property, it behaves like a check box.
If the grid contains too many grid columns to display at once, WinStudio automatically supplies horizontal scroll bars. If you want a particular grid column to be locked in place and displayed in spite of scrolling, you must set the Locked From Scrolling property in the Component properties sheet.
