When RadGridView is displaying a self-referencing it should be able to show the data with ColumnGroupsViewDefinition and HtmlViewDefinition.
Hi, I wrote a new message in the post with a solution: http://www.telerik.com/forums/view-definition-and-hierarchical-grid
For them time being we cannot engage with a time frame when this feature will be available. It is a major task that would request a lot of resources.
Thank you for the understanding.
When will this be available?
