Hello Ama,
You can achieve the desired behavior by allowing the column menu to handle the Name column, but disable its checkbox programmatically in the columnMenuInit event.
http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#events-columnMenuInit
On a side note, if the user should not hide a particular column, probably there is a reason why he wouldn't want to do that, so explicitly disabling the checkbox is not required, since the column can be easily displayed back, if hidden by accident.
