class RadGridExport : RadGrid

We are using the native PDF export features of the RadGrid control.  I would like to be able to insert an image (corporate logo) into the beginning of the pdf file (above the data table data).

I found the OnPDFExporting() event and decided to override it and thus access the RawHTML stream. 
I then attempted to add an image to the HTML via the <img> element:

protected override void OnPdfExporting(GridPdfExportingArgs e)

{

base.OnPdfExporting(e);

string newHTML = string.Empty;

string addHTML = string.Empty;

newHTML = e.RawHTML;

//THIS WORKS

addHTML =

@"<img alt='test' src='../images/corp_logo.gif'/>";

//THIS DOES NOT WORK (where URL is correct and resolvable)

addHTML =

@"<img alt='test' src='https://mycorp.net/pages/Custom/Images/corp_logo.gif'/>";

newHTML = addHTML + newHTML;

e.RawHTML = newHTML;

}

The issue that I am running into is that the above technique will work as long as I am using a relative path that resolves within the directory structure of the web application / virtual directory.

However, if I used an absolute path (via http:/ or file:/ or even embedded by data:) that I get an error similar to:

"System.SystemException: Error while creating area : Encountered web exception while fetching image from file:///C:/WORKING/MyProject/MyProject.Controls/Test/https://mycorp.net/pages/Custom/Images/corp_logo.gif: The given path's format is not supported."

Even though I have manually coded the src attribute with a absolute path to a URL... the RadGrid appears to resolve to my web apps directory structure.

Is there any way that I can avoid this behavior and have the src attribute work against an absolute?

Or is there another technique or method recommended for adding an image to a PDF file that is being exported?

Thanks,

I ran the first application from the Training Guide (PDF page 34), and I am getting the below error about the web.config file and using the SmartTag to configure this control as well as the RadScriptManager control:

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

Where does this control belong on the page and how do I fix the web.config so that this lesson can run in the browser correctly?

Thanks,
