How to reset DatagridView Combo box cell On the DatagridView Combo Box SelectedIndexChanged change event

Question

"This is all about reset Data Grid View combo box cell when i change the Another data grid combo box Cell"

Example :: If i have four rows in DataGridView they all including combo box If i select value in all of them Than i just change the value in first rows any combo box cell so respective event should reset all cells below from his position

Is it possible! Or any suggestion

What if its the second row, so first row should be reset ? Does it imply than only one row with all ComboBox selected should occur ? — V4Vendetta, Jul 22 '11 at 09:04

foreach (Control field in container.Controls)
{
    if (field is ComboBox)
        ((ComboBox)field).SelectedIndex = 0;
    else
        dgView.DataSource = null;
        ClearAllText(field);
}

it will reset their initial position

private void Grid_ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    int X_access = -1;
    int Y_access = -1; 

    // Reset DatagridView ComboBox cell On the DatagridView ComboBox
    if (dataGridView_preView.CurrentCell.RowIndex == 0)
    {
        X_access = dataGridView_preView.CurrentCellAddress.Y; // find Cell position 
        Y_access = dataGridView_preView.CurrentCellAddress.X;
        dataGridView_preView.Rows[X_access + 1].Cells[Y_access].Value = ""; // reset
        dataGridView_preView.Rows[X_access + 2].Cells[Y_access].Value = "";
        dataGridView_preView.Rows[X_access + 3].Cells[Y_access].Value = "";
    }

    else if (dataGridView_preView.CurrentCell.RowIndex == 1)
    {
        dataGridView_preView.Rows[X_access + 1].Cells[Y_access].Value = "";
