Hi Sabrina,
To disable/hide the TabbedMDIManager''s context-menu, you can handle the BeforePopup event to cancel the popup.
Here is the code snippet:
//Handling the BeforePopup Event
this.tabbedMDIManager.ContextMenuItem.BeforePopup += new CancelEventHandler(ContextMenuItem_BeforePopup);
private void ContextMenuItem_BeforePopup(object sender, CancelEventArgs e)
{
e.Cancel = true;
}
Here with I attach a Sample for your reference:

Please let me know if this helps you.Thanks for your interest in Syncfusion products.
Best Regards,
Seetha
