Hi Terrance,

Thank you for posting in the community.

I suggest that you take a look at the following resources from our documentation on the subject of displaying hierarchical data in UltraWebGrid:

http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.1/CLR4.0/html/WebGrid_Binding_WebGrid_to_a_WebHierarchicalDataSource.html

http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.1/CLR4.0/html/WebGrid_Display_Hierarchical_Data.html

Please note, however, that the UltraWebGrid control is now outdated and as of .NetAdvantage 2011 Volume 2 is no longer included in our product package. I would suggest that you consider switching to the WebDataGrid/WebHieararchicalDataGrid. More information regarding these controls is available at:

http://help.infragistics.com/NetAdvantage/ASPNET/2011.2/CLR4.0/?page=Web_WebDataGrid_WebDataGrid.html

Additional samples demonstrating the features of these grids can be found at:

Feel free to contact me if you have any questions.
