By default, the ToolTipText property will contain the value of of the UltraListViewItemBase.Text property when the ToolTip is being displayed for UltraListViewSubItem, and when the ToolTip is being displayed for an UltraListViewItem when the TipStyle property is set to 'Show'. When the TipStyle property is set to 'Automatic' the value of the UltraListViewItem instance's UltraListViewItemBase.Text property is displayed if it is not fully visible in the user interface. Additionally, the value of the UltraListViewColumnBase.TextResolved property of the UltraListViewSubItemColumn, along with the value of the UltraListViewItemBase.Text property of the corresponding UltraListViewSubItem, is displayed for each of the UltraListViewSubItemColumn instances which are to be displayed as determined by the VisibleInToolTip and SubItemsVisibleInToolTipByDefault properties. The visible order in which the sub-items are displayed is determined by the VisiblePositionInToolTip property.
