推荐答案

由于您正在谈论GridView，因此我将其视为ASP.NET问题.
您需要在GridView中删除并选择CommandField列.

选中此所有GridView [

Since you are talking about GridView, I will consider it as an ASP.NET question.
You need Delete and Select CommandField columns in your GridView.

Check this All-in-one GridView[^] example from CodeProject.

Hope this helps!

string str = GridView1.DataKeys [e.NewSelectedIndex] .Value.ToString();
SqlCommand cmd =新的SqlCommand(从表名中删除，其中id = @ id"，con);
cmd.Parameters.AddWithValue("@ id"，str);
con.Open();
cmd.ExecuteNonQuery();
con.Close();

string str = GridView1.DataKeys[e.NewSelectedIndex].Value.ToString();
SqlCommand cmd = new SqlCommand("delete from tablename where id=@id", con);
cmd.Parameters.AddWithValue("@id", str);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
