Not directly. The Height property is set to read only.

 Try setting colHeaderLines to the maximum 10 value in form designer.

Example:

UltraGridBand1.ColHeaderLines =10

or use Rowlayouts to get access to height property. Be aweare that any group layout you might have dissappear from displaylayout when implementing rowlayout.

But it is possible to create unbound columns and place them on top of bound columns to achieve a Group look with groupheaders. Just remember to set Labelposision to LabelOnly.
