标题: datagridview checkbox默认勾选
         DataTable dt = new DataTable();
         dt.Columns.Add("姓名", Type.GetType("System.String"));
         dt.Columns.Add("性别", Type.GetType("System.String"));
         dt.Columns.Add("年龄", Type.GetType("System.Int32"));

         dt.Rows.Add(new object[] { "甲", "男", 22 });
         dt.Rows.Add(new object[] { "乙", "女", 20 });
         dt.Rows.Add(new object[] { "丙", "女", 21 });
         dt.Rows.Add(new object[] { "丁", "女", 22 });
         dataGridView1.DataSource = dt;

         DataGridViewCheckBoxColumn checkColum = new DataGridViewCheckBoxColumn();
         checkColum.HeaderText = "Select";
         checkColum.Name = "Select";
         checkColum.DataPropertyName = "Select";

         checkColum.ReadOnly = false;
         checkColum.TrueValue = true ;
         checkColum.FalseValue = false;

         dataGridView1.Columns.Add(checkColum);

         for (int i = 0; i < dataGridView1.Rows.Count; i++)
         {
            dataGridView1.Rows[i].Cells["Select"].Selected = true;或者dataGridView1.Rows[i].Cells["Select"].Value = true;
         }
         网上都是用以上方法，测试发现无效，有经过测试过的方法没？
