I have a basic asp.net page with an image upload loaded through an iframe:
      <asp:Panel runat="server">
            <asp:TextBox runat="server" id="imgCaption" CssClass="imgCaption" PlaceHolder="caption(optional)" />
    
            <asp:FileUpload runat="server" ID="programmImages" Width="200px" CssClass="offScreen" />
 
            <asp:Button runat="server" id="hiddenImageUpload" OnClick="UploadImage" CssClass="insButton" Text="Upload" />
       </asp:Panel>
 
the image upload depends on the route data in order to upload but whenever i try to upload the image i get this error:
 
> Object reference not set to an instance of an object
 
on this line:
 
var ProgName = Page.RouteData.Values["prog"].ToString()
;
 
this line works fine in other pages.
 
so how can i retrieve the route data through the iframe.
 
Thanks
