I have four tables and i am getting data from these four table in gridview rowediting , I have used NExtResult  in my code when i execute the store procedure it shows two records but when the code vb.net execute after the next result it does not loop through the next row mean that it just showing the first row below is the code and i have 4 select statement that is why i am using next result () method , my Districts are 10 means ten rows when i execute stored procedure but when the code runs i.e. in edit mode i have to checked the checkboxlist item whose value are present in db it just check the first checkboxlist item mean the while loop ends after nextresult method
