>What is higlighting expression. Seems it's true (highlight color) for all cells in combo row. I use highlighted class in files\classes section (Two grid classes).

Just standard stuff, works everywhere else, including checkboxes, containers, edit boxes, etc., and works fine for "hidden" combo boxes, too. Note that this grid has some editable text fields, so I don't think I can use a special highlighting class here.

select mycursor
topmain.recnum = recno()
this.SetAll("DynamicBackColor",;
"IIF(recno()=topmain.recnum,;
topmain.colorb,;
'')", "Column")
this.SetAll("DynamicForeColor",;
"IIF(recno()=topmain.recnum,;
topmain.colorf,;
'')", "Column")
