Idea is very sipmple
Simple query
Select idkey,text from mytable
html query
Select '<p>'||cast(idkey as varchar(10))||'</p><p>'||text||'</p>' as html_info from mytable
I can use any html tag and grid will show it correctly. Very nice.
Question was about image. I can use img tag but I need load pict from db filed not from file.
