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:
radRibbonBar1.HelpButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
All the best,
the Telerik team
