.net - 当用户取消添加过程时，如何删除正在添加的DataGridView行？

Question

我有一个数据绑定(bind) DataGridView。当添加新行并且用户按下 Esc 我想删除整行。我该怎么做？

Answer 1

其实很简单

private void dataGridView1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == (char)27)
    {
        if (dataGridView1.Rows.Count > 0)
        {
            dataGridView1.Rows.RemoveAt(dataGridView1.Rows.Count - 1);
            MessageBox.Show("Last row deleted!");
        }
        e.Handled = true;
    }
}

但请记住:

Rows cannot be programmatically removed unless the DataGridView is data-bound to an IBindingList that supports change notification and allows deletion
