The RadGridView is a UI Component whose main purpose is to visualize the bound collection of items. It is up to you to decide and make the initial setup of your application. The control has a default behavior that does not depend on the database you are using from your side. With this in mind, we do not provide specific examples for the different data sources. You can check how to populate the control with data on the following article from our documentation page - Populating with Data - Overview
. You can find information regarding the different events on the following article - Events Overview
I also suggest you to download the Telerik WPF SDK Samples Browser which you can find at http://demos.telerik.com/xaml-sdkbrowser/
. Once you have it installed, you can browse through lots of examples that represent different scenarios. Since you are interested in the GridView control, simply check the different demos regarding it.
