We have a content editor that uses the RadEditor for edit and display of HTML. Recent versions of the ASP.NET AJAX have caused this display problem for content blocks that contain a tag like <title /> instead of the correct <title></title>. Edge and Chrome do not like the <title /> and suppress the remainder of the page.

 

The sample test case content is simply

   <html>
   <head>
   <title />
   </head>
  </html>

 

 Older versions of the RadEditor modify the title to prevent the issue:

   <textarea id="ctl00_AdminContent_ContentEditor1_RadEditor1ContentHiddenTextarea" name="ctl00$AdminContent$ContentEditor1$RadEditor1" rows="4" cols="20" style="display:none;">

   %3chtml%3e
   %3chead%3e
   %3ctitle /%3e
   %3c/head%3e
   %3c/html%3e

   </textarea>

The current RadEditor versions emit a div instead of a textarea:

   <div id="ctl00_AdminContent_ContentEditor1_RadEditor1" class="RadEditor Web20 reWrapper" style="height:400px;width:680px;">
   <html>
   <head>
   <title />
   </head>
   </html>
   </div>

The working version is 2015.3.930 and failing versions are 2016.2.607 and 2016.3.914.

Regarding the <title /> issue, please see http://stackoverflow.com/a/196249

Thanks,

Gary Davis

Hi Gary,

I tested both versions the old 2015.3.930 and the latest one 2016.3.914 and reproduced similar results:

<html>
    <head>
        <title>
    </head>
</html>
</title>
</head>
<body>
</body>
</html>


Here is a video demonstration: http://screencast.com/t/nCyA45eP4fbn.

As you can see the latest version also offers a hidden textarea element as the old version.

You can implement a custom content filter that will strip the unwanted tags in the content area of RadEditor: Custom Content Filters.

Best regards,

How do I get the new version to use the hidden textarea instead of the div?

In any case, I have updated my few hundred content blocks in the database to use the correct HTML title tag with a closing tag.

Thanks,

Gary Davis

Hello,

The latest version should use a hidden text area by default, since the editor uses it to encode the content and to submit it as part of the form.
