I have already solved my problem.
I did not add any columns to the ListView, directly added elements and I
never got vertical scroll bar. The view appeared like 'List' type that we
get in the file open dialog. So the elements were one below other till we
got to bottom and then in the next column and so on... It was never
vertically scrollable.
Now I have added a column to the ListView with no header, and make the
column width equal to the width of listview client and I get a nice list
which has all the elements one below other with vertical scrollbar to the
right.
Sorry for the confusion, the property I meant was 'View'.
Thanks,
