            DataGridView1.Columns.Add(column3)
            DataGridView1.Columns.Add(column4)
            Dim comboCell As DataGridViewComboBoxCell
            Dim i As Short
            i = 0

                DataGridView1.Rows.Add()



                comboCell = DataGridView1.Item(0, i)
                comboCell.Items.Item(i).text = ("Role_Name")
                If oRsRead("Role_Name") = "NormalUser" Then
                    comboCell.Items.Add("Administrator")
                Else
                    comboCell.Items.Add("NormalUser")
                End If

                comboCell.Items.Item(i).text = ("Region_Name")
                If oRsRead("Region_Name") = "US" Then
                    comboCell.Items.Add("CANADA")
                Else
                    comboCell.Items.Add("US")
                End If

                comboCell = DataGridView1.Item(2, i)
                comboCell.Items.Item(i).text = ("SEGMENT_NAME")
                If oRsRead("SEGMENT_NAME") = "Commercial" Then
                    comboCell.Items.Add("Consumer")
                Else
                    comboCell.Items.Add("Commercial")
                End If

                i = i + 1
            End While
