在DataGridView中单击单元格时使用ComboBox text /value fill

private void Form1_Load(object sender, EventArgs e)
{
    dataGridView1.CellClick += DataGridView1_CellClick;
}

private void DataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    // 判断是否单击了ComboBox所在的列（假设为第2列）
    if (e.ColumnIndex == 1)
    {
        // 创建一个ComboBox控件
        ComboBox comboBox = new ComboBox();

        // 获取单元格的文本和值
        string cellText = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
        string cellValue = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();

        // 填充ComboBox的文本和值
        comboBox.Items.Add(new ComboBoxItem(cellText, cellValue));
        comboBox.DisplayMember = "Text";
        comboBox.ValueMember = "Value";
        comboBox.SelectedIndex = 0;

        // 将ComboBox控件添加到单元格中
        dataGridView1.Controls.Add(comboBox);
        comboBox.Location = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, false).Location;
        comboBox.Size = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, false).Size;
        comboBox.Visible = true;
    }
}

public class ComboBoxItem
{
    public string Text { get; set; }
    public string Value { get; set; }

    public ComboBoxItem(string text, string value)
    {
        Text = text;
        Value = value;
    }
}
