Value	Meaning
tlbeDefault	Expand buttons are displayed within the first visible bottom band if none of the other bands are set as tlbeExpandable.
tlbeExpandable	The band displays expand buttons. If multiple bands are set as tlbeExpandable, the first visible bottom band will display expand buttons. If the categorized paint style is applied to the TreeList control, the expandable band is always considered to be the first visible bottom band.

Use the ActuallyExpandable property to determine whether the current band or one of its child bands displays expand buttons. To access the band that displays expand buttons, use the TreeList control’s Bands.ExpandableBand property.

The default value of the Expandable property is tlbeDefault.
