i facing 1 issue highcharts.

    $('#container').highcharts({     exporting: {                             buttons: {                                 contextbutton: {                                     enabled: false                                 },                                 exportbutton: {                                     text: 'download',                                     y:30,                                     //x: 1,                                     //y: 5,                                     // use download related menu items default context button                                     menuitems: highcharts.getoptions().exporting.buttons.contextbutton.menuitems.splice(2)                                 },                                 printbutton: {                                     text: 'print',                                     y: 30,                                     onclick: function () {                                         this.print();                                     }                                 }                             }                         }        });

this code working fine when call once, when call again without refreshing page, download button not show me options such download pdf, download image etc.

any help?

thanks.

that line culprit:

highcharts.getoptions().exporting.buttons.contextbutton.menuitems.splice(2)

splice modifies array. after first call, menuitems isn't same. use slice() instead:

highcharts.getoptions().exporting.buttons.contextbutton.menuitems.slice(2)

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
