DataGridView not populating based on DataTable values

I have a DataGridView that isn't populating correctly. I basically load a datagridview with data. Then, I execute a procedure that creates a DataTable based on the dgv and it's data.

Once the DataTable is built with the data, I clear the dgv, and then assign the DataTable as it's DataSource. The correct amount of rows are present but the cells are empty. See the attached screenshot. My code is below where I create the DataTable and assign it as the DGV's datasource.


        Private Sub CreateLoadTestDataTable()
        Try
            Dim colCnt As Integer = dgvLoadTests.Columns.Count
            Dim strCol As String = ""

            dtLoadTest = New DataTable

            For x As Integer = 0 To colCnt - 1
                strCol = "Col"
                strCol &= x + 1
                dtLoadTest.Columns.Add(strCol)
            Next

            For x As Integer = 0 To rowCnt - 1
                Dim row As DataRow
                row = dtLoadTest.NewRow

                For y As Integer = 0 To colCnt - 1
                    strCol = "Col"
                    strCol &= y + 1
                    row(strCol) = dgvLoadTests.Rows(x).Cells(y).Value
                Next

                dtLoadTest.Rows.Add(row)
            Next

            dgvLoadTests.AutoGenerateColumns = False
            dgvLoadTests.DataSource = Nothing
            dgvLoadTests.DataSource = dtLoadTest

        Catch ex As Exception
            EH.strRetVal = gfrmID & "/CreateLoadTestDataTable() - " & ex.Message
        End Try

        EH.ProcessMessages(Me, sbr, EH.strRetVal)
    End Sub
