Errors with hierarchal grid

[Nate Pinchot]

Hello,
As instructed (please reference this post http://www.telerik.com/community/forums/thread/b311D-bbddmm.aspx) I am attempting to use the RadGrid from Prometheus however it seems there is a bug in it with heirarchal grids. I have added the Prometheus Grid to my page (and removed the old ASP .NET one and the references to those controls) and I get an error when attempting to add columns to my DetailTable. If I select my grid, expand MasterTableView in the properties, click on the DetailTables collection, click the Add button, click on the Columns collection (in misc), then click the Add button I get the message "Cannot create an instance of Telerik.Web.UI.GridColumn because it is an abstract class." If I am doing something wrong please let me know.

I also tried bypassing the GUI and converting my old RadGrid code to Prometheus by simply changing the prefix of everything from radG to telerik however then when I try to load the page I get an error message of "Destination array is not long enough to copy all the items in the collection. Check array index and length."

I have included my Prometheus Grid code below in case I have done something wrong, however please be aware that all this code was generated through GUI options /selections (not hand made). I realize this is not a hierarchal grid in the code below, because I can't make one because of errors in the GUI.
