If you are using the new Bind() method, but are trying to pass it to a function or perform any other type of manipulation on it, you will get the following error as Bind() only allows for 1 way data binding:

Bind does not exist in the current context

Instead, you will need to use the following format:

Data Source (C#)
DataReader: ((System.Data.Common.DbDataRecord)Container.DataItem)[]
DataSet: ((System.Data.DataRowView)Container.DataItem)[]

Data Source (VB.NET)
DataReader / DataSet: Container.DataItem()

One other option is to use Eval().
