Accessing Ignored Class Properties during ItemDataBound

[TB]

(re-wording a previous post.. this makes much more sense, sorry for any
duplication)

First off, I've got three classes:

Class MyItem
Public PropertyOne As String
Public PropertyTwo As String
Public PropertyThree As String
Public ItemError As MyItemError
End Class

Class MyItemError
Public ID As Int32
Public Description As String
End Class

Class MyItemCollection
Inherits ArrayList
End Class

I'm populating a MyItemCollection with several instances of the MyItem
class, and then binding MyItemCollection to a data grid. I'm creating
templated columns and only displaying PropertyOne and PropertyTwo from each
MyItem.

Is it possible to access the other properties of this class (i.e.
PropertyThree or ItemError.ID) from within the ItemDataBound event of the
DataGrid??

TIA - TB
