Hi All
I am using Visual Studio 2008/C#.
The page consists of an ASP:Treeview. The treenodes are populated with
the contents of a selected directory consisting of a number
of .doc/.xls/.txt/.pdf documents. The user can then select a document
(by clicking) and the document will open up in the browser. This works
well in IE 7.0. In IE 8.0 and IE 9.0 The directory is read and the
nodes populated correctly but the document links will not work at all.
The document links do not work in Mozilla either.
Can anyone shine a light on the problem ? I would appreciate any input
I can get.
Many thanks in advance
Regards
Iain Wilson
