Thank you for writing.
Our RadGridView control supports such a layout. The feature is called self-reference hierarchy. Here you can find its documentation: http://www.telerik.com/help/winforms/gridview-hierarchical-grid-self-referencing-hierarchy.html
. In addition you can check out the GridView demos in our demo application for an example.
I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
