Property Value

Type	Default	Description
Boolean	false	true if the column is visible; otherwise, false.

Remarks

If the Visible property is set to true, the column is visible within the Tree List. The position at which it’s displayed within the column header panel is specified by the TreeListColumn.VisibleIndex property. Otherwise, if the Visible property is set to false, the column is invisible. In this instance, the column’s header is displayed within the Customization Form, provided that the column’s TreeListOptionsColumn.ShowInCustomizationForm option is enabled.
