Name cannot begin with the '-' character, hexadecimal value 0x2D

[Kyle Jones]

Hey,

I am having problems with your ExportToPdf() method.  When I try to invoke it like you do in your demo I get this error : "

Name cannot begin with the '-' character, hexadecimal value 0x2D".  Why is this happening?

Thank,

Kyle

I believe this is happening because your editor contains non-valid XHTML code. For more information on the exporting feature read over this article. Basically the editor content is created as a XHTML table and then converted to .pdf so if there are non-valid tags then this function will produce an error.

Hi Kyle,

If you still get this error you might also wish to check your page encoding - try setting it to UTF8 if it is not already set to that.

All the best,

Hello Octavio,

Note that RadEditor's content will be rendered as an XHTML table and then convert that table to a PDF document. That requires that the rendered output is valid XHTML. If it is not, you will receive an exception that the export cannot be completed.

Therefore I can suggest you to verify that the RadEditor's content is valid. If you cannot handle that, it is better to open a support ticket and send us a fully runnable sample with reproduction steps of the issue, so we can investigate in on our side.

Regarding the link of the mentioned article it has been updated and moved to PDF Export link. Note that the RadEditor and RadGrid uses the same mechanism for PDF export so that handling similar issues may be reliable to both controls.

Hello Kamran,

As already mentioned in this forum thread - such problem might occur if the content that you are trying to export is not XHTML compliant. Could you please verify that this is the case? If so, I recommend you to check the content of the editor using the W3C Validation dialog and correct the errors.

Also, you might wish to check your page encoding - try setting it to UTF8 if it is not already set to that.

If non of the above solves the problem, could you please provide the problematic content so we can investigate it locally?

Congratulations
The uploaded document "RadEditorContent.html" was successfully checked as XHTML 1.1. This means that the resource in question identified itself as "XHTML 1.1" and that we successfully performed a formal validation of it. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).

"valid" Icon(s) on your Web page
To show your readers that you have taken the care to create an interoperable Web page, you may display this icon on any page that validates. Here is the HTML you could use to add this icon to your Web page:

Valid XHTML 1.1
  <p>    <a href="http://validator.w3.org/check?uri=referer"><img      src="http://validator.w3.org/http://www.w3.org/Icons/valid-xhtml11" alt="Valid XHTML 1.1" height="31" width="88" /></a>  </p>  A full list of icons, with links to alternate formats and colors, is available: If you like, you can download a copy of the icons to keep in your local web directory, and change the HTML fragment above to reference your local image rather than the one on this server. See also our help items related to documents transferred over secure protocols for these icons and the "uri=referer" feature.

Validating CSS Style Sheets
If you use CSS in your document, you can check it using the W3C CSS Validation Service.
