Is it possible to call the code command from c# to javascript function? -

this tricky me , don't know how solve one.. have 2 identical database table [table1,table2] want transfer database item database , delete data previous database avoid duplication.. used listbox1 , listbox2 after transfer data, next step want save changes.. have insert code on c# , i'm using on asp.net problem after transfer item listbox1 listbox2 click save changes button item move listbox2 go listbox1 run c# code -_- delay? think submit first before run c# code.. save code save same items :-/

that's why come idea of calling c# code function since javacript comes first .. if have better idea please share

here's tranfer item javascript code

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>     <script type="text/javascript">         $(function () {             $("#left").bind("click", function () {                 var options = $("[id*=rightbox] option:selected");                 (var = 0; < options.length; i++) {                     var opt = $(options[i]).clone();                     $(options[i]).remove();                     $("[id*=leftbox]").append(opt);                 }             });             $("#right").bind("click", function () {                 var options = $("[id*=leftbox] option:selected");                 (var = 0; < options.length; i++) {                     var opt = $(options[i]).clone();                     $(options[i]).remove();                     $("[id*=rightbox]").append(opt);                 }             });         }); </script> 

here's save c# code

  (int = leftbox.items.count - 1; >= 0; i--)        {            //◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘ ◘add◘ ◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘             string[] splits = leftbox.items[i].tostring().split(new char[] { '-' });            string id_split = splits[0];             conn.close();            conn.open();            string str = "select * user_table_list id='" + id_split + "'";            sqlcommand com = new sqlcommand(str, conn);            sqldatareader reader = com.executereader();            if (!reader.read())            {                reader.close();                sqlcommand cmd = new sqlcommand("insert user_table_list (id, firstname,middlename,lastname,age,sex) values (@id, @fname, @mname, @lname,@age,@sex)", conn);                cmd.parameters.add("@id", sqldbtype.nvarchar).value = splits[0].toupper();                cmd.parameters.add("@fname", sqldbtype.nvarchar).value = splits[1].toupper();                cmd.parameters.add("@mname", sqldbtype.nvarchar).value = splits[2].toupper();                cmd.parameters.add("@lname", sqldbtype.nvarchar).value = splits[3].toupper();                cmd.parameters.add("@age", sqldbtype.nvarchar).value = splits[4].toupper();                cmd.parameters.add("@sex", sqldbtype.nvarchar).value = splits[5].toupper();                cmd.executenonquery();             }            conn.close();              //◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘ ◘delete◘ ◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘◘             conn.close();            conn.open();            string str8 = "select * user_table_list2 id='" + id_split + "'";            sqlcommand com8 = new sqlcommand(str8, conn);            sqldatareader reader8 = com8.executereader();            if (reader8.read())            {                string id = reader8["id"].tostring();                reader8.close();                string sql9 = "delete [user_table_list2] id='" + id + "'";                sqlcommand cmd9 = new sqlcommand(sql9, conn);                cmd9.executenonquery();                 conn.close();             }        }    }
