Hello,

 I used the code of Linda Liu :

http://groups.google.it/group/microsoft.public.dotnet.framework.windowsforms.des
igntime/browse_thread/thread/a3de0c7d8d53c3a5/733038e531a523d3?hl=it&lnk=st&q=da
taGridView+vertical&rnum=8#

 It works, but I have some problems when the dataGridView have the
Orizzontal Scroll Bar.
 The Orizzontal Scroll Bar appear in the DataGridView when
 there are a lot of columns or when I resize the window.

 If I move the orizzontal sroll-bar from left to right
 the vertical oriented text of the columns header are show correct,
 but if I move the orizzontal sroll-bar from right to left
 the vertical oriented text are trunc and
 it is impossible to read the columns Headers.

 If I move again the orizontal scroll-bar from left to right
 the vertical oriented text of the columns header are show correct.
 The vertical oriented text are also show correct if I go over with
the mouse pointer.

 It seem that there isn't a correct refresh.

 I tried in different computers and I have always the same error.

 Do you know any solutions to resolve this problem?

Thanks a lot,
 CLO
