Hi Santhosh Kumar Bathruswamy,
There is no direct API available to hide the specific RibbonToggleButton that handles the LayoutMode in the Ribbon control. However, we’ve prepared a solution that achieves your requirement by setting the visibility of this button through a code-behind approach.
Please let us know if you need any further assistance or clarifications.
Regards,
Sekar Sivalingam
