Datagridview combobox column problem

I have a grid that has a column of comboboxes.  I'm pulling from a database for three separate conditions and filling three datasets.  I want to bind these datasets to one particular column, but only every third cell.  In other words, row one should bind to ds1, row 2 to ds2, row 3 to ds3, row 4 to ds1, row 5 to ds2, etc.

I am doing this

        For rw As Integer = 0 To 23 Step 3
            Dim cell As New DataGridViewComboBoxCell
            cell.DataSource = dsslide1
            dgvNewJob.Rows(rw).Cells(1) = cell
         Next

        For rw As Integer = 1 To 23 Step 3
            Dim cell As New DataGridViewComboBoxCell
            cell.DataSource = dsslide1
            dgvNewJob.Rows(rw).Cells(1) = cell
         Next

I get errors and the box does not contain any data.

Any ideas what I am doing wrong?

I found the answer to load different values in comboboxes in the same column of a datagridview.
            'fill slide and type 1
            For rw As Integer = 0 To 23 Step 3
                Try
                    Dim cell As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dsslide1.Tables(0).Rows.Count - 1
                        cell.Items.Add(dsslide1.Tables(0).Rows(cnt).Item("description"))
                    Next
                    JobGrid.Rows(rw).Cells(1) = cell
 
                    Dim cell1 As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dstype1.Tables(0).Rows.Count - 1
                        cell1.Items.Add(dstype1.Tables(0).Rows(cnt).Item("description"))
                    Next
                    JobGrid.Rows(rw).Cells(7) = cell1
                Catch ex As Exception
                    errlog.WriteError("Error in filling slide1 and type1: " & ex.Message, "LoadNewJob")
                End Try
            Next
 
            'fill slide and type 2
            For rw As Integer = 1 To 23 Step 3
                Try
                    Dim cell As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dsslide2.Tables(0).Rows.Count - 1
                        cell.Items.Add(dsslide2.Tables(0).Rows(cnt).Item("description"))
                    Next
                    JobGrid.Rows(rw).Cells(1) = cell
 
                    Dim cell1 As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dstype2.Tables(0).Rows.Count - 1
                        cell1.Items.Add(dstype2.Tables(0).Rows(cnt).Item("description"))
                    Next
                    JobGrid.Rows(rw).Cells(7) = cell1
                Catch ex As Exception
                    errlog.WriteError("Error in filling slide2 and type2: " & ex.Message, "LoadNewJob")
                End Try
            Next
 
            'fill slide and type 3
            For rw As Integer = 2 To 23 Step 3
                Try
                    Dim cell As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dsslide3.Tables(0).Rows.Count - 1
                        cell.Items.Add(dsslide3.Tables(0).Rows(cnt).Item("description"))
                    Next
                    JobGrid.Rows(rw).Cells(1) = cell
 
                    Dim cell1 As New DataGridViewComboBoxCell
                    For cnt As Integer = 0 To dstype3.Tables(0).Rows.Count - 1
                        cell1.Items.Add(dstype3.Tables(0).Rows(cnt).Item("description"))
                    Next

                    errlog.WriteError("Error in filling slide3 and type3: " & ex.Message, "LoadNewJob")
                End Try
