dataGridView1.ReadOnly = true ;      //禁用編輯功能

方法一：通過手動新增Datatable，再繫結dataGridView

DataTable dt = new DataTable();//建立個數據表

dt.Columns.Add(new DataColumn("id", typeof(int)));//在表中新增int型別的列

dt.Columns.Add(new DataColumn("Name", typeof(string)));//在表中新增string型別的Name列

DataRow dr;//行
for (int i = 0; i < 3; i++)
{
      dr = dt.NewRow();
      dr["id"] = i;
      dr["Name"] = "Name" + i;
      dt.Rows.Add(dr);//在表的物件的行裡新增此行
}

dataGridView1.DataSource =dt;

如果要新增一個textbox效果的列，可做如下處理

dt.Columns.Add(new DataColumn("選中", typeof(bool));

方法二：直接在dataGridView中插入

        dataGridView1.ColumnCount = 4;
        dataGridView1.ColumnHeadersVisible = true;

        // Set the column header style.
        DataGridViewCellStyle columnHeaderStyle = new

 DataGridViewCellStyle();

        columnHeaderStyle.BackColor = Color.Beige;
        columnHeaderStyle.Font = new Font("Verdana", 10, FontStyle.Bold);
        dataGridView1.ColumnHeadersDefaultCellStyle = columnHeaderStyle;

        // Set the column header names.
        dataGridView1.Columns[0].Name = "Recipe";
        dataGridView1.Columns[1].Name = "Category";
        dataGridView1.Columns[2].Name = "Main Ingredients";
        dataGridView1.Columns[3].Name = "Rating";

        // Populate the rows.
        string[] row1 = new string[] { "Meatloaf", "Main Dish", "ground beef",
            "**" };
        string[] row2 = new string[] { "Key Lime Pie", "Dessert", 
            "lime juice, evaporated milk", "****" };
        string[] row3 = new string[] { "Orange-Salsa Pork Chops", "Main Dish", 
            "pork chops, salsa, orange juice", "****" };
        string[] row4 = new string[] { "Black Bean and Rice Salad", "Salad", 
            "black beans, brown rice", "****" };
        string[] row5 = new string[] { "Chocolate Cheesecake", "Dessert", 
            "cream cheese", "***" };
        string[] row6 = new string[] { "Black Bean Dip", "Appetizer", 
            "black beans, sour cream", "***" };
        object[] rows = new object[] { row1, row2, row3, row4, row5, row6 };

        foreach (string[] rowArray in rows)
        {
            dataGridView1.Rows.Add(rowArray);
        }

插入DataGridViewCheckBoxColumn列

DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn();
{
        column.HeaderText = "選中";

        column.Name = isSelected;

        column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
        column.FlatStyle = FlatStyle.Standard;
        column.ThreeState = true;
        column.CellTemplate = new DataGridViewCheckBoxCell();
        column.CellTemplate.Style.BackColor = Color.Beige;
    }
 DataGridView1.Columns.Insert(0, column);
