We are still on an older version of the controls for .net 2.0 and cannot upgrade for another month or two.  We need to implement the filtering that ConvertInlineStylesToAttributes does now though.  Could you provide some javascript that would allow us to run this type of cleanup now? 

Hello,

The ConvertInlineStylesToAttributes is a complex filter and it is not so easy to be implemented in an earlier builds.

As being an owner of Developer License with subscription you can download the source code of Telerik.Web.UI.dll and implement your own custom content filter using as a base the code of the ConvertInlineStylesToAttributes filter. This filter is located in the \Editor\RadEditor\EditorFiltersManager.js. It also use the convertAttribute, convertBorderAttribute, convertCSSProperty and convertTypeAttribute functions the declarations of which are available in the \Editor\RadEditor\0EditorUtils.js file.
