I would first try using the properties of the PDF and setting the initial view to the "Pages panel and page".
There is no documented method. You could try setting the documents 'pane' property to "T".
this.pane = "T";
Thanks for your reply, but the 'pane' property is not what I am after.
You can use the Action or Batch Processing feature of Acrobat Professional to set the "Initial View" parameters or there are some 3rd party tools that can alter the initial view.
