How to detect the composing message format selection is switched? RRS feed

  • Question

  • Dear Professionals,

    Please let me know how to detect the action that the selected state of the option buttons "Format" (HTML, Plain Text or Rich Text) on a message compose inspector ribbon is just switched.

    I want to switch a control's Enabled state depending on that buttons state with C# VSTO.
