-

i got 3 fragments each on seperate tab. on 1 tab want have fragment in card-style. 1 row should [ ________ ________ +]. after pressing +button want second identical row appear. how achive that? professional way manipulate tagfragments during runtime? how can implement trancisions?

i got it. can add additional rows by: 

@override     public void onclick(view v) {         switch (v.getid()) {         case r.id.imagebuttonadd:             if(i==0){                 raisecounterbyone();                 counter.settext(counterstart.tostring());                 test = getactivity().findviewbyid(r.id.testview3);                 test.setvisibility(view.visible);                 i++;             } else if(i==1){                 raisecounterbyone();                 counter.settext(counterstart.tostring());                 test = getactivity().findviewbyid(r.id.testview4);                 test.setvisibility(view.visible);                 i++;             }             break;         case r.id.imagebuttoncancel2:             log.d("","close");             test = getactivity().findviewbyid(r.id.testview3);             test.setvisibility(view.gone);             i--;             break;         case r.id.imagebuttoncancel3:             log.d("","close");             test = getactivity().findviewbyid(r.id.testview4);             test.setvisibility(view.gone);             i--;             break;         default:             break;         }     }

is there better way more flexible? array or loop? there opportunity put views array? want set maximum number of rows can added. furthermore index each row later use.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
