One of the strengths of DotNetNuke is the ability to modify the Providers
and swap out functionality on a large scale with ease. A common change is to modify the HTML Provider, this page shows you how to do so.
If you are on DotNetNuke 5.4+ and have upgraded from a previous version of DNN you are likely still using the FCK Editor, you can enable the new Telerik Rad Editor provider by following the instructions below.
Enabling the Telerik RAD Editor in DNN requires you to make a simple change to the DotNetNuke web.config file that can be found in the root of your website on the file system. When you open the file up find the following section of the web.config file
You will need to change the defaultProvider=”FckHtmlEditorProvider” setting to be defaultProvider=”TelerikEditorProvider”
Once you’ve done that simply save the changes to the web.config file and reload your website! Then any modules that use the standard DNN text editor control should be using Telerik instead of FCK.
