How to store the value from radiobuttonlist to database in C# ASP.NET -


i need in storing values radiobuttonlist sql server 2008. code works fine when checked in database if values radiobuttonlist have been stored there's nothing in database.

asp.net 

    <p>        hypertension<asp:radiobuttonlist          id="radiobuttonlist1"          repeatcolumns ="2" repeatdirection = "vertical"          repeatlayout= "table" runat="server"          autopostback="true"           onselectedindexchanged="radiobuttonlist1_selectedindexchanged"           width="250px" height="10px" style="margin-left: 0px" borderstyle="none"            cellpadding="1" cellspacing="1">           <asp:listitem value="rbtrue">true</asp:listitem>        <asp:listitem selected="true" value="rbfalse">false</asp:listitem>       </asp:radiobuttonlist>    </p>

in c#:

    protected void button1_click(object sender, eventargs e)     {         //response.redirect("webform1.aspx");         string selectedvalue1 = this.radiobuttonlist1.selectedvalue;         string selectedvalue2 = this.radiobuttonlist2.selectedvalue;          using (sqlconnection conn = new sqlconnection(configurationmanager.connectionstrings["tumorregistryconnectionstring1"].connectionstring))         {             string sql = "insert tbtrcbase(hpn,hpntreatement,ish,ishtreatment,asthma,asthmatreatment,dm,dmtreatment,otherco,othercotreatment,secondhandsmoke,smoker,stopsmoking,occupation,cancerfamilyhistory,familywithcancer,parentwithcancer) value(@d1,@d2,@d3,@d4,@d5,@d6,@d7,@d8,@d9,@d10,@d11,@d12,@d13,@d14,@d15,@d16,@d17)";              sqlcommand cmd = new sqlcommand();             cmd.connection = conn;             cmd.commandtype = commandtype.text;             cmd.commandtext = sql;             cmd.parameters.addwithvalue("@d1", selectedvalue1);             cmd.parameters.addwithvalue("@d2", selectedvalue2);              try             {                 if (conn.state != connectionstate.open)                     conn.open();                 int result = cmd.executenonquery();             }             catch (exception ex)             {                 response.write(ex.message);                 return;             }           }       }

if use 

string selectedvalue2 = this.radiobuttonlist2.selectedvalue;

you value of list button selected rbtrue or rbfalse

if want selected radiolistbuttons text use this

 string selectedvalue2 = this.radiobuttonlist1.selecteditem.text;

try query 

string sql = "insert tbtrcbase(hpn,hpntreatement,ish,ishtreatment,asthma,asthmatreatment,dm,dmtreatment,otherco,othercotreatment,secondhandsmoke,smoker,stopsmoking,occupation,cancerfamilyhistory,familywithcancer,parentwithcancer) values(@d1,@d2,@d3,@d4,@d5,@d6,@d7,@d8,@d9,@d10,@d11,@d12,@d13,@d14,@d15,@d16,@d17)";

hope helps

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
