Access DataGrid AutoGenerate BoundColumns?

I am trying to access the details on columns that were added to a ASP.NET DataGrid via autogenerate. The DataGrid.Columns collection only contains the details that were specified in the HTML/Design mode. I specifically want the BoundColumn object for an auto-generated DataGrid column.<br><br>In the debugger, I see a DataGrid.autoGenColumnsArray collection, but this is a private variable. As far as I can tell, there is no property or method to access this collection. This has what I want, it is basically the collection of DataGrid columns that were created during auto-generate.
