Hello Marco,

Let Us know if you have any questions with this matter.

Hi,

There is no way to toggle the visibility of a tool in the ribbon directly.  However, you can use the Ribbons "ToolsNotInRibbon" collection to hold onto tools that do not currently have a place in the ribbon.  If you need to toggle visibility one way to do it would be to remove a tool from it's group and add it to the ToolsNotInRibbon collection until you need it for a group again.

Another option is to use a custom style to set the visibility to collapsed as needed.  Unfortunately the ability to dynamically toggle the visibility of tools was not one of our targeted use cases.
