c# - OnPropertyChanged between windows - WPF -


before all, i'm sorry english not native. so, developing wpf application, thow windows, 1 present many button records on db , little form add new one, have 1 problem. when add record db onpropertychanged not fire , new buttons doesn't show up, think because datacontext.

lugareswindow.xaml

 <itemscontrol itemssource="{binding lugaresbtns}" margin="0,35,0,0">             <itemscontrol.itemspanel>                 <itemspaneltemplate>                     <uniformgrid columns="7" />                 </itemspaneltemplate>             </itemscontrol.itemspanel>             <itemscontrol.itemtemplate>                 <datatemplate>                     <grid>                         <button content="{binding numero}" click="openlugar" tag="{binding idlugar}" horizontalalignment="left" margin="10,10,0,0" verticalalignment="top" width="96" height="30"/>                     </grid>                 </datatemplate>             </itemscontrol.itemtemplate>         </itemscontrol>

lugareswindow.xaml.cs

private void addlugarbtn_click(object sender, routedeventargs e) {     //(datacontext lugarviewservice).addlugar("11","6969","a","","1"); **if use works!**     editlugarwindow window = new editlugarwindow(-1);     window.show();  }

editlugarwindow.xaml.cs (confirm form add new record)

        if (lvs.addlugar(idparquetxt.text, numerotxt.text, sectortxt.text, matriculatxt.text, selected))         {             this.close();         }

and on lugarviewservice.cs

   public bool addlugar(string idparque, string numero, string sector, string matricula, string tipo)     {         int newnumero, newtipo, newparque;          try         {             newparque = int.parse(idparque);             newnumero = int.parse(numero);             newtipo = int.parse(tipo);             pmclient.addlugar(newparque, newnumero, sector, matricula, newtipo, 1);                            onpropertychanged("lugaresbtns");             return true;         }         catch (exception e)         {             messagebox.show("erro ao adicionar. por favor verifique o numero de lugar ou o tipo\n" + e.message);             return false;         }     }   public list<lugar> lugaresbtns {         {         return pmclient.getlugaresbyparque(idparque).tolist();      } }

so, can see, lugareswindow.xaml doesnt updated after insert new record using window. doing wrong?

thank all!

it's solved, had set window.datacontext lvs instance using. thak replies.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
