I have problem with the encoding (done in c#) the database returns is invalid:

(your grid popup a xml error box)

This is what FireFox says about the xml file: 

XML Parsing Error: not well-formed

Location: [127.0.0.1/mes/pluginpage.aspx?PI ... eXmlList=1](http://127.0.0.1/mes/pluginpage.aspx?PIPID=ABB.MES.Recipe&RecipeXmlList=1)

Line Number 836, Column 17:Rødvin S&P 11% 

I have no clue at the moment how I can solve this, however if I mask this "Rødvin" out the result is just fine.

Try using another encoding
(ISO-8859-1 for example). Plus the value of R�dvin S&P 11% 
contains & symbol which is not allowed. You should change it to &
