C# 调用项并将其添加到datagridview中的新组合框中

在我的程序中，在datagrid视图的前两行中有一些带有可变编号（取决于用户选择）的组合框。现在我想添加项并在其他类中使用它们，但我没有访问它们的权限，因为在创建之前我不知道如何调用它们？（它们是在运行时创建的）

//我就是这样创建它们的：

for (int j = 0; j < columncount; j++) {
    dataGridView1.Rows[i].Cells[j] = new DataGridViewComboBoxCell();
}

for（int j=0；j

行代码的演示怎么样

  public Form0114()
        {
            InitializeComponent();
            Combox();
        }
        public void Combox()
        {
            dataGridView1.ColumnCount = 3;
            dataGridView1.Columns[0].Name = "Product ID";
            dataGridView1.Columns[1].Name = "Product Name";
            dataGridView1.Columns[2].Name = "Product Price";
            string[] row = new string[] { "1", "Product 1", "1000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "2", "Product 2", "2000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "3", "Product 3", "3000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "4", "Product 4", "4000" };
            dataGridView1.Rows.Add(row);
            DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn();
            cmb.HeaderText = "Select Data";
            cmb.Name = "cmb";
            cmb.MaxDropDownItems = 4;
            cmb.Items.Add("True");
            cmb.Items.Add("False");
            dataGridView1.Columns.Add(cmb);
        }
