Hello Lyuba,

How would that work where there are no fixed levels. One of the parents has children 5 levels deep and the other has 9.

In my scenario, I might be looking at 17 levels deep for a few parents.

The examples in the help section use Access/SQL DataSource, which I cannot in my case.

I have the data in a single dataset, I've attached a screenshot of the table. It's flat and the key is on 'EVENT_ID,LOGICAL_NAME,LOGICAL_PARENT_NAME'. The table shows only until level 2, but down the line there will be more than 15 levels.

What is the best way for me to use this in memory data set and create self reference and display the names of servers in a hierarchical tree structure? 

this is on VS 2008 ASP.NET || Infragistics35.Web.v10.1|| VB.NET || ORACLE

Thanks,
