Hi, Try like this if (Convert.ToInt32(ds.Tables[0].Rows[0]["total"]) == 0) { //do your code } Regards, Iftikar

try like this: if(ds.Tables[1].Rows[0]["total"].ToString() == "0") or if (Convert.ToInt32(ds.Tables[0].Rows[0]["total"]) == 0) { //your code } please give details of your requirement . what you need in this line

First check ds.Tables[1] exist and do either if(ds.Tables[1].Rows[0]["total"].ToString() == "0") or if(int.parse(ds.Tables[1].Rows[0]["total"].ToString()) == 0)
