Have a look at this topic, which explains how to Customize the Localization of filter dropdown options. I believe you will find this guide very helpful. As for the edit row Done and Cancel, we provide online sample that is showing how to change the appearance of the entire Row.
I believe you will benefit a lot from our forum and online samples, you can find a lot of solutions and custom implementations that may have a positive impact not only on your application but on the knowledge of our ASP.NET product that you have as well.
