According to Telerik...
The default behavior of RadGridView control is to generate its columns automatically based on the underlying data source. This means that when you set the ItemsSource of the RadGridView control to a collection of employees for example, a separate column will be created for each one of the public properties of your Employee object. This is the default behavior and it does not require any additional efforts from your side. Just set the ItemSource of your RadGridView and you are ready.

Therefore all your properties will be automatically generated. If you read this page (and the rest of the documentation) it states quite clearly how to generate the columns you need.
A quick edit.. This guide will also help point you to a QUICK way to "Not auto-generate a column" http://www.telerik.com/help/wpf/gridview-prevent-column-autogenerate.html
