Binding VB.net DataRepeater to dataview items at runtime with aggregation using linq

Question

Hoping someone can help me out with what is probably a dumb question.

I'm trying to use a datarepeater to display data generated via LINQ from a datatable

I've managed to do this fine with a filtered existing datasource using:

Me.Tbl_52TableAdapter.Fill(Me.CBRDataSet.tbl_52)

Dim query =
  From dlist In CBRDataSet.tbl_52.AsEnumerable
  Where (dlist.Field(Of String)("TL") = "CTS 06")
  Select dlist

query.CopyToDataTable().AsDataView()
DataRepeater1.DataSource = query

The problem being that I need to aggregate a field in the dataset into a count.

If I replace the query with:

Dim query =
  From CountAgent In CBRDataSet.tbl_52.AsEnumerable
  Group CountAgent By PBX = CountAgent.Field(Of String)("TL") Into Count()
  Select Count

It then states that: 'CopyToDataTable' is not a member of 'System.Collections.Generic.IEnumerable(Of Integer)'

I've tried to get around it by changing the declaration to: Dim query As IEnumerable(Of DataRow) =

Which compiles, but I have no idea if it works, and I cant check as I can't find a way to bind a label to the produced count col of the dataview.

If anyone can tell me what I'm doing wrong i'd be most appreciative.

Coming back to my own question, in case it helps anyone else: MSDN had the answer - You need to overload copyToDataTable as described in

"How to: Implement CopyToDataTable Where the Generic Type T Is Not a DataRow" on:
