Hello Marco,
The common control ListView as defined in Windows itself and implemented
in
.NET Framework does not support multi-line column headers. If you still
want
to implement this, you can consider coding a control inheriting from
System.Windows.Forms.ListView, or use owner-draw to user paint the column
headers. You could reference
http://www.codeproject.com/cs/miscctrl/customheader.asp for the latter.
