c# - Syncfusion's SfSchedule doesn't handle different item types -


situation: got syncfusion sfschedule control in ui. bind list of appointments itemssource this:

<schedule:sfschedule x:name="mycalendar"                      itemssource="{binding appointments}"                      ... />

my appointments property list of objects implement interface wrote:

private observablecollection<icalendaritem> _appointments; public observablecollection<icalendaritem> appointments {     => _appointments;     private set => set(ref _appointments, value); }

i have 2 implementations icalendaritem: singlecalendaritem , repetitivecalendaritem.

problem: syncfusion's schedule control works , displays appointments long appointments list contains of 1 of calendar item types only, instance singlecalendaritem or repetitivecalendaritem.

the second add both object types list, schedule control displays nothing. continues display nothing if bound list consists of objects of type singlecalendaritem only.

question: looks syncfusion sfschedule control gets hiccup once bound item source list consisting of multiple types though implement same interface. able confirm bug in sfschedule and/or knows workaround how can bind different objects?

i bug in syncfusion's sfschedule control (as of august 2017). found workaround: built facade holds of icalendaritem objects , exposes interface properties , methods:

public class calendaritemfacade : icalendaritem {     private icalendaritem _calendaritem;     public calendaritemfacade(icalendaritem calendaritem)     {         _calendaritem = calendaritem;     }      public datetime starttime => _calendaritem.starttime;     // other interface implementations follow here }

instead of assigning list of of different calendar item types sfschedule property, ensure of facade type calendaritemfacade.

update: reported bug syncfusion: https://www.syncfusion.com/support/directtrac/incidents/185839. syncfusion confirmed issue. bug fixed since 14/9/2017 apparently - tested.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
