Answer 1

后台应该怎么写,不再js中做操作
public static string GetBasicInfoTypes(SqlConnection cn, string VTNAME, string CNAME, string CSNAME, String VendorCode)
        {
            StringBuilder sb = new StringBuilder();

            string SCNAME = StringHelper.EmptyOrUnescapedStringViaUrlDecode(CNAME);
            string SCSNAME = StringHelper.EmptyOrUnescapedStringViaUrlDecode(CSNAME);
            sb.Append(@"

            if (SVTNAME.Equals(string.Empty) || SCNAME.Equals(string.Empty) || SCSNAME.Equals(string.Empty))
            {
                return "";
            }
            else

                using (SqlDataReader dr = cmd.ExecuteReader())
                {
                    dt.Load(dr);
                }
            }
            return JsonConvert.SerializeObject(dt);
        }

Answer 2

 protected void GridView1_你的行XXX事件(object sender, EventArgs e)
{
if（e.RowIndex <= 3）
{
......
}
else
{
......
}
}

Answer 3
