Row specific filtering of DataGridViewComboBox data source.

I had a specific situation where I need to bind a combo box's data source in a grid view had to be filtered based on a value in the row. Here is how I have done the same. I have not assigned any datasource to DataGridViewComboBox column, instead I have assigned DataSource to each of the DataGridViewComboBoxCell. Hope this is right. :)

    public partial class DemoGridView : Form

    {

        private
string[] names = new
string[] { "ABC",
"XYZ", "UVW"
};

        public
DemoGridView()

        {

            InitializeComponent();

        }

        private
void Form1_Load(object
sender, EventArgs e)

        {

            DataSet
data = BuildDemoData();

            AddColumns(data);

            dataGridView1.DataSource =
data.Tables["DemoData"];

            SetFilteredList(data,
dataGridView1);

        }

        private
void SetFilteredList(DataSet
data, DataGridView demoGrid)

        {

            DataViewManager
viewManager = new DataViewManager(data);

            demoGrid.AllowUserToAddRows = false;

            demoGrid.AllowUserToDeleteRows = false;

            for
(int i = 0; i < demoGrid.Rows.Count; i++)

            {

                DataGridViewComboBoxCell
comboCell = demoGrid[3, i] as DataGridViewComboBoxCell;

                DataView
cellView = viewManager.CreateDataView(data.Tables["Mod3Numbers"]);

            cellView.RowFilter = "FilterID = " + demoGrid[0,
i].Value.ToString();

                comboCell.DataSource =
cellView;

            }

        }

        private
void AddColumns(DataSet
data)

        {

            DataGridViewTextBoxColumn
idCol = new DataGridViewTextBoxColumn();

            idCol.HeaderText = "ID";

            idCol.DataPropertyName = "ID";

            idCol.Visible = false;

            DataGridViewTextBoxColumn
nameCol = new DataGridViewTextBoxColumn();

            nameCol.HeaderText = "Name";

            nameCol.DataPropertyName = "Name";

            DataGridViewComboBoxColumn
monthCol = new DataGridViewComboBoxColumn();

            monthCol.DataSource = data.Tables["Months"];

            monthCol.DisplayMember = "Name";

            monthCol.ValueMember = "ID";

            monthCol.DataPropertyName = "Month";

            DataGridViewComboBoxColumn
fidCol = new DataGridViewComboBoxColumn();

            //FIDCol.DataSource
= data.Tables["Mod3Numbers"].DefaultView;

            fidCol.DisplayMember = "Name";

            fidCol.ValueMember = "ID";

            fidCol.DataPropertyName = "FID";

            dataGridView1.Columns.Add(idCol);

            dataGridView1.Columns.Add(nameCol);

           
dataGridView1.Columns.Add(monthCol);

            dataGridView1.Columns.Add(fidCol);

        }

        private
DataSet BuildDemoData()

        {

            DataSet
data = new DataSet();

           
data.Tables.Add(GenerateListOfMonths());

            data.Tables.Add(GetListMod3());

            data.Tables.Add(GetMainList());

            return
data;

        }

        private
DataTable GetMainList()

        {

            DataTable
demoTable = new DataTable("DemoData");

            demoTable.Columns.Add("ID", typeof(int));
