I am facing an Security Exception issue.
I am trying to export an pdf file but I am getting this error:

Description: The application attempted to perform an operation not
allowed by the security policy.  To grant this application the
required permission please contact your system administrator or change
the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: That assembly
does not allow partially trusted callers.

Now I am changing the web.config file by setting ASP.NET hosting trust level
but still it is not working:I am getting this Parser error:
Parser Error Message: This configuration section cannot be used at
this path. This happens when the site administrator has locked access
to this section using <location allowOverride="false"> from an
inherited configuration file.

This the code I am adding in web.config file:

XML

<location allowOverride="true">
    <system.web>
      <securityPolicy>
       <trustLevel name="Full" policyFile="internal" />
      </securityPolicy>
      <trust level="Full" originUrl="" />
     </system.web>
   </location>

And I have also tried with these trust level one by one:

XML

<trustLevel name="High" policyFile="web_hightrust.config" />
<trustLevel name="Medium" policyFile="web_mediumtrust.config" />
<trustLevel name="Low" policyFile="web_lowtrust.config" />
<trustLevel name="Minimal" policyFile="web_minimaltrust.config" />
<trustLevel name="Custom" policyFile="web_CustomTrust.config" />

But still it is not working
Please can help fixing this.By the way I am hosted in Godaddy.

I am not using any folder.This is the my code to export the pdf.

protected void ExportPDF_Onclick(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=OrderDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
this.Page.RenderControl(tw);
StringReader sr = new StringReader(sw.ToString());
Document Orderpdf = new Document(PageSize.A4, 10f, 10f, 0f, 0.0f);
HTMLWorker htmlparser = new HTMLWorker(Orderpdf);
PdfWriter.GetInstance(Orderpdf, Response.OutputStream);
Orderpdf.Open();
htmlparser.Parse(sr);
Orderpdf.Close();
Response.Write(Orderpdf);

Response.End();

"This happens when the site administrator has locked access
to this section using <location allowOverride="false"> from an
inherited configuration file."

If you are the administrator of that web server, find that file with that setting and change that first.
If you are not the administrator, find him and tell him.

What I am doing is export a pdf file for more than one order detail but the the name of the pdf file is not changing but the content change depend of the order selected by the user it is called OrderDetails.pdf
Now my kestion is Do I need to upload that file in live also.Because in my local I can export and my local system allow me to open that file.But not in live.
