Configuring RadEditor for ASP.NET AJAX in DNN

HOW-TO
Configure RadEditor for ASP.NET AJAX in DNN

SOLUTION
The RadEditor properties can be changed from the editor configuration file (ConfigFile.xml). The file is located at \DesktopModules\TelerikWebUI\RadEditorProvider\ in your DNN site. For example to increase the allowed max upload file size via the Image Manager add the MaxImageSize property there:

  <property name="MaxImageSize">8000000</property>

You can set all standard properties - string, boolean, width, height, etc listed in this page (except these that are not inherited from System.Web.UI.Control) in the ConfigFile.xml.


The properties that apply to file browser managers such as Document, Image, Template, etc are set with the following syntax in RadEditor for ASP.NET AJAX:

        RadEditor1.DocumentManager.ViewPaths = new string[] { "~/" };
        RadEditor1.DocumentManager.UploadPaths = new string[] { "~/" };
        RadEditor1.DocumentManager.MaxUploadFileSize = 1000;
        RadEditor1.DocumentManager.SearchPatterns = new string[] { "*.pdf,*.doc,*.aspx" };

However, these properties could not be set under the config file of RadEditor for DNN with this syntax. For that reason we decided to use the properties of RadEditor Classic that are meant for the managers configuration, e.g.

Property	Description
DeleteDocumentsPaths	String array which contains the paths where the RadEditor will be able to delete documents. The default value is empty string array. The elements of this array must be a subset of the DocumentsPaths array.
DocumentsFilters	String array which contains the file extension filters that control which files are shown in the Document Manager dialog. The default filters are *.doc, *.pdf. There are two allowed wildcards: * - zero or more characters ? - exactly one character
DocumentsPaths	String array which contains the paths where the RadEditor will look for documents. The default value is empty array. These folders will be visible in the file browser part of the dialog.
MaxDocumentSize	The maximum document file size in bytes, allowed for uploading.
UploadDocumentsPaths	String array which contains the paths where the RadEditor will be able to upload documents. The default value is empty string array. The elements of this array must be a subset of the DocumentsPaths array.

The properties that accept a list of values such the above ones should be set as follows in the ConfigFile.xml file:

<property name="DocumentsPaths">
   <item>~/Path1</item>
   <item>~/Path2</item>
   ...etc.
</property>

To set the documents filters property in the editor ToolsFile file use the following syntax:

<property name="DocumentsFilters">
  <item>*.doc</item>
  <item>*.pdf</item>
  <item>*.txt</item>
  <item>*.jpg</item>
  <item>*.gif</item>
</property>

All properties that end with *Paths or *Filters (DocumentsPaths, ImagesFilters, etc.) should be set in this way.
