Can you share which version of Kendo UI for jQuery do you use? The Dojo example that you send me uses the Kendo UI for jQuery version from 2015 which doesn't have the functionality provided by our latest product releases.
If you check this Dojo example, you will see that columns have a "lockable" property definition set to "false". With this property, the Grid will prevent the "locked" column to be unlocked and the "unlocked" columns from being locked. With this configuration, the columns inside the Grid will continue to be reorderable, which, if I understand your description correctly, is what you need to implement in your application.
You can test the linked Dojo. If it demonstrates what you need in your application, I would recommend upgrading your project to the latest Kendo UI for jQuery version.
I hope the above will help you implemented the desired functionality.
