I am trying to have the Css Class dropdown auto populate when using dynamic css.

With a static stylesheet it works fine:

ce.EditorWysiwygModeCss = "~/CuteEditor_Support/Default.css"

But when using an aspx file which generates the stylesheet it does not work:

ce.EditorWysiwygModeCss = "~/CuteEditor_Support/Default.aspx"

When I use the dynamic method the styles are applied to the editor window but the css dropdown is not populated. If I was to hazard a guess I would say that the file is read as a text file and that the aspx file has not yet been rendered.

Is there any workaround for this issue?
