Problem with Pdf not getting rotated inside Surface

Hi i am using surface to open PDF file in wedbrowser control. the PDF file gets opened but webBrowser doesnt get rotated.

string filepath = @"C:\Users\suresh.k\Desktop\WpfPDFViewer\bin\Debug\Files\SSRS.pdf";

public Window2()
{
InitializeComponent();
WebBrowser1.Navigate(new Uri(filepath));
}



Tried with binding"Adobe PDF Reader" into windows user control, which gets showed by means of WindowsFormsHost control.(Doesnt rotate here also)

string filepath = AppDomain.CurrentDomain.BaseDirectory + @"Files\SSRS.pdf";
var uc = new UserControl1(filepath);
this.windowsFormsHost1.Child = uc;



Please suggest one solution to overcome the problem
