You Have to Try this
Dim strautoid As String = GridView1.Rows(e.RowIndex).Cells(1).Text() instead of this ,try below
TableCell cl = GridView1.Rows[e.RowIndex].Cells[1];
(Label) lbl=(Label).cl.FindControl("Your Label ID");
Dim strautoid As String=lbl.Text;

I haven't checked this exactly, but you need something like:
我还没有完全检查过这个，但你需要这样的东西：
Dim lblCell as label = GridView1.Rows(e.RowIndex).Cells(1).FindControl("labelID")
Dim strautoid As String = lblCell.Text
As i say, haven't checked exactly but the key to getting this correct is in the FindControl method, i hope that helps.
正如我所说，还没有完全检查过，但正确检查的关键在于 FindControl 方法，我希望能有所帮助。
