No worries. The mistake here is main.
The e.Value property from the PastingCellClipboardContent event arguments contains only the copied data string because during the copy of a cell only this is saved. The reason behind this behavior is that the data should be readable from any application that supports pasting and usually those application doesn't have information for the RadGridView's cell or the underlying business object.
To achieve your requirement, you can use also the copy events of RadGridView (Copying, CopyingCellClipboardContent and Copied) where you can save information for the copied cell and use it in the PastingCellClipboardContent event.
