Devexpress GridView增加CheckBox列

参考DEV官网代码做了一个增加checkbox列效果：

#region 方法：设置GridView数据绑定
        public void GridDataBind()
        {
            dt = dbHelper.Fill(cmdStr);                     // 填充DataTable
            dt.Columns.Add("Check", typeof(bool));  // 增加个CheckBox列
            dt.Columns["Check"].SetOrdinal(0);       // 设置选择列的位置
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                dt.Rows[i]["Check"] = false;
            }
            gridControl1.DataSource = dt;
            gridView1.Columns["Check"].Width = 22;
            gridView1.Columns["Check"].OptionsColumn.ShowCaption = false;
            gridView1.Columns["Check"].OptionsColumn.AllowSort = DevExpress.Utils.DefaultBoolean.False;
        }
  #endregion

在窗体加载事件里的代码：

private void MainForm_Load(object sender, EventArgs e)

{

#region 从本地数据库中获取数据 并展示到gridView控件上

GridDataBind();

#endregion

#region 设置gridview列只读（不能编辑）

for (int i = 1; i < gridView1.Columns.Count; i++)

{

gridView1.Columns[i].OptionsColumn.ReadOnly = true;

}
