c# - Different types of treeview items to be binded in one single data template -


i have mvvm based usercontrol. model has 2 classes, 1 class has list of type class shown in model below. problem i have 2 define 2 different hierarchicaldatatemplates treeview binded model wrong. make 1 hierarchicaldatatemplate know property in viewmodel. in end, want treeview like:

|familyname

||personname

||personname

the code quite big, have taken pieces. if more info required please let me know:

model

public class family { private string m_name; public string nameoffamily     {         { return m_name; }         set { m_name= value; }     }      public observablecollection<person> persons{ get; set ; } }  public class person { private string m_name; public string nameofperson     {         { return m_name; }         set { m_name= value; }     }   }

in viewmodel received family respective persons e.g.

viewmodel

family fam = getfamilywithrespectivepersons;

view

<treeview name="mytreeview" grid.column="0" width="auto" height="300" itemssource="{binding fam}">    <treeview.resources>       <hierarchicaldatatemplate  datatype="{x:type classes:family}" itemssource="{binding persons}">                                               <treeviewitem header="{binding nameoffamily}"></treeviewitem>                                                     </hierarchicaldatatemplate>        <hierarchicaldatatemplate  datatype="{x:type classes:person}">                                                                         <treeviewitem header="{binding nameofperson}"></treeviewitem>                                                                          </hierarchicaldatatemplate>  </treeview.resources> </treeview>

it not wrong define datatemplate per type. since person class has no children, datatemplate doesn't have hierarchical.

also, templates shouldn't include treeviewitem elements:

<treeview name="mytreeview" grid.column="0" width="auto" height="300" itemssource="{binding fam}">     <treeview.resources>         <hierarchicaldatatemplate  datatype="{x:type classes:family}" itemssource="{binding persons}">             <textblock text="{binding nameoffamily}" />         </hierarchicaldatatemplate>         <datatemplate datatype="{x:type classes:person}">             <textblock text="{binding nameofperson}" />         </datatemplate>     </treeview.resources> </treeview>

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

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
