Thank you for writing.
You can change RadGridView
visual appearance and behavior by using a view definition. Please refer to the following help article: http://docs.telerik.com/devtools/winforms/gridview/view-definitions/overview
Additionally, you can have a look at our Demo application >> GridView >> Columns >> Grid Views
example which is quite useful on this topic.
I hope this information helps. Should you have further questions I would be glad to help.
Do you need help with upgrading your AJAX, WPF or WinForms project? Check the Telerik API Analyzer
