不可選、可以設置ReadOnly =true ; 你現在要求是有條件讓它可選。那可以在Form_Load 事件遍歷整個列、設置 ReadOnly 屬性。

代碼：

  public partial class FormDemo : Form
    {
        public FormDemo()
        {
            InitializeComponent();
            this.Load += new EventHandler(Form3_Load);
        }

        void Form3_Load(object sender, EventArgs e)
        {
            DataTable table = new DataTable();

            table.Columns.Add("IsTrue", typeof(bool));
            table.Columns.Add("Code");
            table.Columns.Add("Name");

            DataRow row = null;

            row = table.NewRow();
            row["IsTrue"] = 1;
            row["Code"] = "001";
            row["nAME"] = "001";
            table.Rows.Add(row);

            row = table.NewRow();
            row["IsTrue"] = 0;
            row["Code"] = "002";
            row["nAME"] = "002";
            table.Rows.Add(row);

            row = table.NewRow();
            row["IsTrue"] = 1;
            row["Code"] = "003";
            row["nAME"] = "003";
            table.Rows.Add(row);

            row = table.NewRow();
            row["IsTrue"] = 0;
            row["Code"] = "004";
            row["nAME"] = "004";
            table.Rows.Add(row);

            this.dataGridView1.DataSource = table;

            for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
            {
                this.dataGridView1.Rows[i].Cells[0].ReadOnly = true;
            }
        }
    }

可以在行綁定事件中獲取列的值，如果達到要求，則查找到此控件設置相關屬性。
