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;
}
#endregion
