winform中的 DataGridView 的 AllowUserToDeleteRows属性怎么设置?

//store the selected row index.
        private int selectedRowIndex = 0;
        public Form1() {
            InitializeComponent();
        }
        //Initialize the Data.
        private void Form1_Load(object sender, EventArgs e) {
            string strConnection = @"Data Source=.\SQLExpress;Initial Catalog=DB_Person;Integrated Security=True";
            using(SqlConnection connect = new SqlConnection(strConnection)) {
                SqlCommand cmd = connect.CreateCommand();
                cmd.CommandText = "select * from [T_Employee]";
                DataSet set = new DataSet();
                SqlDataAdapter adapter = new SqlDataAdapter(cmd);
                adapter.Fill(set, "T_Employee");
                dataGV.DataSource = set.Tables["T_Employee"];   //specify the DataSource.
                dataGV.ReadOnly = true; //read only not work when trying to delete or add rows.
                //can not add or delete rows.
                dataGV.AllowUserToAddRows = false;
                dataGV.AllowUserToDeleteRows = false;
            }
        }
        //Try to delete the DataGridView row.
        private void btn_DeleteRow_Click(object sender, EventArgs e) { 
 
            dataGV.Rows.Remove(dataGV.Rows[selectedRowIndex]);
        }
        //Get the index of the selected row.
        private void dataGV_CellClick(object sender, DataGridViewCellEventArgs e) {
            selectedRowIndex = dataGV.CurrentCell.RowIndex;
        }
//我做的测试很简单.但是我不解的是,怎么还是可以删除行...

[解决办法]
你说的可以删除 是不是你点那个删除行按钮的时候 可以删除？
AllowUseToDeleteRows属性只是在DataGridView里面执行行删除，那是它本身带有的功能，就像它的排序一样，而你通过删除按钮来删除这样肯定可以，所以说你禁止的只是DataGridView里面的删除功能
[解决办法]
AllowUseToDeleteRows这个属性是这么用的，启用时候：在DataGridView中选中行，按Delete键可以删除选中行数据；不启用时：按Delete键无效。
非DataGridView内操作是不控制的。

AllowUserToDeleteRows对于用户体验就有效果，如果对代码是无效的！！

Add 和Delete属性都一样,对代码无效的?
这两个都一样么?...
[解决办法]
如果你从代码上去操作，那就是无效的！
AllowUserToDeleteRows和AllowUserToAddRows是针对用户体验的！！
