Thank you for writing.
I assume that you want to create grid with hierarchy. If so you can read more about hierarchical grid in our online documentation: http://www.telerik.com/help/winforms/gridview-hierarchical-grid-tutorial-binding-to-hierarchical-data.html
There is demo in our Demo application. You can take a look at hierarchical grid in action, in section GridView >> Hierarchy.
I hope this information helps. Should you have any other questions, I will be glad to assist you.
