Thanks, I did rebuild and tried publishing website, recycle, restart, stop and start nothing helps. I have no idea yet what could be the problem.
For testing its a simple label, when I set text in ascx file it displays but when I do it from ascx.cs, nothing is shown. when I comment out whole databind method nothing unusal happens, eveything displayed in order totals. What I am doing wrong, I think its just overlooking but..... where??
