Hi
I am trying to find documentation about how to work with RadRibbonBar Help button.
We are using version 2011.2.11.712.
Does anyone have a link or document how to work with this?

Hello Fokko, 

Thank you for writing.

Currently, we do not have documentation about this button. It is just a help button (RadImageButtonElement) with a predefined image and you can add some functionality (like showing help) when the button is clicked. You can make this button visible by using the following code snippet:

I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
 
All the best,
Stefan
