将组合框选择绑定到datagridview的当前行

// 创建一个DataGridView控件
DataGridView dataGridView1 = new DataGridView();

// 设置DataGridView的数据源为一个数据表
DataTable dataTable = new DataTable();
dataGridView1.DataSource = dataTable;

// 添加一个列，类型为DataGridViewComboBoxColumn
DataGridViewComboBoxColumn comboBoxColumn = new DataGridViewComboBoxColumn();
comboBoxColumn.Name = "ComboBoxColumn";
dataGridView1.Columns.Add(comboBoxColumn);

// 数据绑定完成后，为每一行的组合框列设置选项值
dataGridView1.DataBindingComplete += (sender, e) =>
{
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        DataGridViewComboBoxCell comboBoxCell = row.Cells["ComboBoxColumn"] as DataGridViewComboBoxCell;
        comboBoxCell.DataSource = GetComboBoxOptions(row); // 获取当前行的组合框选项值
    }
};

// 处理DataGridView的CellValueChanged事件，更新相关数据
dataGridView1.CellValueChanged += (sender, e) =>
{
    if (e.ColumnIndex == dataGridView1.Columns["ComboBoxColumn"].Index)
    {
        DataGridViewComboBoxCell comboBoxCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex] as DataGridViewComboBoxCell;
        string selectedOption = comboBoxCell.Value.ToString(); // 获取用户选择的选项值

        // 更新相关数据
        UpdateRelatedData(dataGridView1.Rows[e.RowIndex], selectedOption);
    }
};
