Hi, I'm opening new window from Code Behind for that I'm using Code :

Dim newWin As String = ("<script language='javascript'>" + "window.open('msgstat.aspx' , 'Print', 'height=200, width=220, menubar=no, toolbar=no, scrollbars=no, resizable=no'); </script>")

ClientScript.RegisterStartupScript(Me.GetType(), "pop", newWin)

Now, how can I check from codebehind that Browser's Popup Blocker is enabled or Disabled and show such message.
