iFrame not seeing pdf document

Hello,

I am trying to load a pdf document into an iFrame from code behind. I am using the following code in code behind on Page Load:

C#

if (Session["Document"].ToString() != string.Empty)
        {
            string document = Session["Document"].ToString();
            pdfIframe.Attributes.Add("src", document);
        }

It works perfectly when I run it from inside Visual Studio 10 using the internal web-server, but it does not work at all when it is uploaded to the website (it throws an error page) Everything else (eg: database, queries, etc.) works fine.
Any help appreciated.

What I have tried:

I have done a Google search and tried a few different code variations. I changed the web.config file to an earlier version. I have tried to run it in Firefox and IE. No luck.

Which error?

Perhaps, it requires some add-on?

Thank you Afzaal, It is a Runtime Error and I did not see the actual error in the error page. Not sure how to do that but I will look into it today. I will post what it said below.

As to "some add on" ... honestly, that's really way too vague for an answer. As stated, I am using the internal asp.net browser function that comes with Visual Studio 10, and it works perfectly. So I would "assume" that someone with more expertise than I have about Browsers could tell me if I need to add something to the program for it work on standard type browsers. If that's the case, then knowing which add on is required would be the answer that I am looking for. The only other way I can think of to resolve the problem is not to use pdf's and instead do a 'database' pull for the information as text and post it to a text area (not very pretty); and that seems like a very poor compromise. Thanks again for your input. I'm all ears if you can follow up on this. Best Regards, Pat

Following Up; although I am still trying to get a read out of the page error (unsuccessful so far), I thought of switching to a Google Docs reader to see if the error might be with the Adobe reader (not uncommon). Again, it works perfectly in the VS 2010 environment, but it still throws a runtime error of some kind since it is now referring to an error page that I have put in to the web.config file. I'll show the new code below, buy I do not think it is a coding problem (this coming from someone that obviously cannot fix it!). I feel it has something to do with the web.config file (just a hunch if you will). PLEASE, as I continue to try to get an error readout, someone MUST have seen an issue like this before. Any idea's are welcome. Thank you, Pat.

C#

//Using iFrame with Google Docs
        if (Session["Document"].ToString() != string.Empty)
        {
            string document = Session["Document"].ToString();
            string pdfPage = "http://docs.google.com/gview?url=" + document + "&embedded=true";
            pdfFrame.Attributes.Add("src", pdfPage);
        }
        else
        {
            ClientScriptManager script = Page.ClientScript;
            if (!script.IsClientScriptBlockRegistered(this.GetType(), "Alert"))
            {
                script.RegisterClientScriptBlock(this.GetType(), "Alert", "alert('Sorry, this document cannot be found. ')", true);
                return;
            }
        }
