我的表单中有一个 DataGridView,并且我将该 DataGridView 绑定(bind)到一个列表。
该列设置为 SortMode=Automatic
。
这是我的代码
List<string> lstLines = new List<string>();
StreamReader sr = new StreamReader(tbFile.Text);
while ((line = sr.ReadLine()) != null)
{
lstLines.Add(line);
}
dgvLines.DataSource = lstLines.Select(x=>new {Text=x}).ToList();
当我单击列标题时,我希望对列进行排序,但什么也没发生。
最佳答案
