My first question is does DNN support right to left support for Telerik RADEditor?

Secondly if I wanted to implement is for just a certain page on my site or have the option such as here with English and Arabic, is this possible?

Many thanks.

I installed DNN6.2.

I don't see Providers\HtmlEditorProviders\Telerik\Config\ToolsDefault.xml files.
I don't see Providers\HtmlEditorProviders directory.

Can someone tell me why?

ok -^--O-O--^- , I managed for DNN 7.0!

1. the XML is now at \DesktopModules\Admin\RadEditorProvider\ToolsFile\toolsfile.xml.
   
   1. I like them handy, so I added them at the beginning:
       <tools name="MainToolbar">
              <tool name="LTR" text="LTR" showtext="true" showicon="false"/>
              <tool name="RTL" text="RTL" showtext="true" showicon="false"/>
      
2. The Js goes to file:  \DesktopModules\Admin\RadEditorProvider\RegisterDialogs.js with a slight change at the end of it.
   
   function SetDirectionOfSelection(editor, strDirection)
               {
                   var rngSelection = editor.getSelection();
                   var strTagNames;
                   strTagNames = "|H1|H2|H3|H4|H5|H6|P|PRE|TD|DIV|BLOCKQUOTE|DT|DD|TABLE|HR|IMG|TR|UL|OL|";
                   if (rngSelection.getParentElement())
                   {
                       var elemSelectionParent = rngSelection.getParentElement();
                       while ((elemSelectionParent != null) && (strTagNames.indexOf("|" + elemSelectionParent.tagName + "|") == -1))
                       {
                           elemSelectionParent = elemSelectionParent.parentNode;
                       }
                       if (elemSelectionParent)
                       {
                           SetDirectionOnElement(elemSelectionParent, strDirection);
                       } 
                       else
                       {
                           var oDoc = editor.get_document();
                           var para = createPara(oDoc, strDirection, editor.getSelectionHtml());
   
                           var range = editor.getSelection().getRange();
   
                           //handle possitioning of the cursor inside the new paragraph
   
                           if ($telerik.isIE)
                           {
                               range.moveToElementText(para);
                               range.select();
                           } 
                           else
                           {

                               range.selectNodeContents(para);
                               editor.getSelection().selectRange(range);
                           }
                           editor.getSelection().collapse();
   
                           SetDirectionOfSelection(editor, strDirection);
                       }
                   }
               }

                   if ("ltr" == strDirection)
                   {
                       element.dir = "ltr";
                       element.align = "left";
                   }
                   else if ("rtl" == strDirection)
                   {
                       element.dir = "rtl";
                       element.align = "right";
                   }
               }
   
               function createPara(doc, dir, content)
               {
                   var par = doc.createElement("P");
                   SetDirectionOnElement(par, dir)
                   par.innerHTML = content;
                   doc.body.appendChild(par);
                   return par;
               }
   
   
   $(document).ready(function() {
     // Handler for .ready() called.
               Telerik.Web.UI.Editor.CommandList["LTR"] = function (commandName, editor, args)
               {
                   SetDirectionOfSelection(editor, "ltr");
               }
               Telerik.Web.UI.Editor.CommandList["RTL"] = function (commandName, editor, args)
               {
                   SetDirectionOfSelection(editor, "rtl");
               }
   
   });
   

I don't know if I overkilled, but I had to restart the site to make it work.
