How can I force my ultragrid bands to be expandable

Question

grid.DisplayLayout.ViewStyle is set to Multiband.

Once upon a time, the application I am working on used to display bands with a "+" and lines connecting the bands (rows and sub rows). When selecting the "+" the bands would toggle appearing and hiding. I did many changes to the grid and somehow this + disappeared and the user can no longer change the appearance of the bands. What could I have possibly done to cause this? Yes I am sure that the ViewStyle is set to Multiband.

The parameter I was looking for was ExpansionIndicator. I could not search for it because I did not know what to call it.

UltraGrid TheGridIron = new UltraGrid();
TheGridIron.DisplayLayout.Override.ExpansionIndicator = Infragistics.Win.UltraWinGrid.ShowExpansionIndicator.Always;
