Hi Peter,
Sounds like your top level rows have columns populated with data inbetween
blank data (columns 7&9)
I would recommend re-ordering the rows so that 7&9 become 6&7.
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_1)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_2)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_3)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_4)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_5)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_6)
APPEND TO ARRAY ($aptr_HierarchyList; ->Column_7)
LISTBOX SET HIERARCHY(*;$vT_ListboxName;True;$aptr_HierarchyList->)
I also like to set the background colour of top level rows to a light grey
and set the font style to bold, using:
$vL_ColumnCount:=Size of array($aptr_HierarchyList->)
For ($vL_ColumnNum;1;$vL_ColumnCount)
OBJECT SET RGB
COLORS($aptr_HierarchyList->{$vL_ColumnNum}->;$vL_BlackColour;$vL_LightGreyColour)
OBJECT SET FONT STYLE($aptr_HierarchyList->{$vL_ColumnNum}->;Bold)
End for //($vL_ColumnNum;1;$vL_ColumnCount)
