WinStudio
When set to True, the No Row Header component property causes the initial column of a grid component to be hidden. (The initial column normally displays the row number for each record displayed.) This property is available only with grid components.
NOTE: When this property is set to True and the initial row is hidden, the active row pointer and status indicators are also hidden. To help overcome this problem, you can use the component property Background Color to indicate the active row. When this property is set to True and the Background Color is set to a color other than white, then the active row displays in the background color.
