This ContextMenu is coming from the control used to edit the cell. When not in edition, your own ContextMenu is shown (the one associated with the cell). When in edition, it is the control’s ContextMenu that is shown.
If you are using the default CellEditorManager (like WinTextBox), it is not possible to override the ContextMenu. However, it is possible using certain other controls, like the .NET TextBox.
