This property's value reflects the name of the .aspx file that contains the server control.

Protected Overrides Sub Render(output As HtmlTextWriter)
   output.Write("Welcome to Control Development!<br>")

   ' Test if the page is loaded for the first time
   If Not Page.IsPostBack Then
      output.Write("Page has just been loaded")
   Else
      output.Write("Postback has occured")
   End If
End Sub
