You are correct. Using DIV, when you scroll down, the column names also scroll. the other way is to have column header outer to the Grid..and have constant width to each of the column. Here you need to set AutoGenerate columns to false and include all columns and respective widths in the data grid. you can refer to this article : http://www.dnzone.com/showDetail.asp?TypeId=2&NewsId=564

You can use for-each statement in xslt and loop thru in xslt. But anyway you have to pass XMLDocument, not XMLNodeList. Pass the XPath as a parameter to XSLT or you can hardcode in xslt if it doesnt change. You can check MSND for how to use for-each statement and Passing parameters to XSLT.
