    Can't bind IEnumerable to DataGridView

    Does anyone know why an IEnumerable might not bind to a DataGridView?

    Thanks,
    Ron

      Ron,

      Is this in System.Windows. Forms or in ASP.NET? If the answer is the
      former, then the requirement is that the collection implement IList, not
      IEnumerable. With ASP.NET, I think you ^should^ be able to bind an
      IEnumerable to a data source, but you would have to check up on that.

          Yes, is't a Win Forms app and I can bind other IEnumerables. Just not sure
          why not this one. Here it is in case you notice anything:

          Public Function GetProgramPrice ListByMedicineI d(ByVal MedicineId) As
          IEnumerable

          Dim y As IEnumerable(Of ProgramMedicine Price)

          y = From pmp In dc.ProgramMedic inePrices _
          Where pmp.MedicineId = MedicineId

          Dim x As IEnumerable
          x = From xy In y _
          Where xy.ProgramMedic inePriceDate = (From test In y _
          Where test.ProgramId =
          xy.ProgramId _
          Select
          test.ProgramMed icinePriceDate) .Max _
          Select xy.Program.Prog ramName, _
          xy.ProgramMedic inePriceDate, _
          xy.ProgramMedic inePriceDollars

          Return x
