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 = "";                  
        dataGridView_preView.Rows[X_access + 2].Cells[Y_access].Value = "";
    }

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

它将重置它们的初始位置
