>What code are you using that you get this error? A DataRow can call it's Delete() method with no problem. Are you doing something peculiar?

I always have to do something like this:

            loDataView = New DataView(loDataProvider.oDataSet.Tables.Item(0))

            loDataView.RowFilter = "Flag=1"

            ' Delete all records which have been flagged
            For Each loRowView In loDataView
                loRowView.Delete()
            Next

            loDataView.RowFilter = ""
            loDataView.Table.AcceptChanges()

            ' Adjust the count
            loDataProvider.nCount = loDataProvider.oDataSet.Tables("Temp").Rows.Count

Because, if I scan my dataset, and based on a condition, I want to remove the record, it will tell me that the Delete() method cannot be used:

            ' For each message
            For lnCounter = 0 To loDataProvider.nCount - 1
                loRow = loDataProvider.oDataSet.Tables("Temp").Rows(lnCounter)

                ' If we have to delete the row
                If True Then
                    loRow.Delete()
                End If

            Next
