xaml - WPF Changing the style of a UserControl in a ListView -


i'm having issues setting style of usercontorl. have usercontrol called busyindicator defined in file. below xaml.

<usercontrol x:class="foo.client.ui.svgs.busyindicator"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"               xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               mc:ignorable="d"               d:designheight="300" d:designwidth="300"              datacontext="{binding relativesource={relativesource self}}"              >     <usercontrol.template>         <controltemplate>             <border width="{binding width}" height="{binding height}" visibility="{templatebinding control.visibility}">                 <canvas width="{binding width}" height="{binding height}"  visibility="{templatebinding  control.visibility}">                     <path fill="{binding foreground}"                           height="25"                           width="25"                           data="m20.519,4.617c-3.262-3.111-7.821-3.965-12.03-2.236 c-4.282,1.76-6.895,5.654-6.863,10.227l3.658-0.025c5.263,9.51,7.017,6.892,9.894,5.71c2.81-1.154,5.85-0.598,8.037,1.456 l-1.395,1.376h5.39v3.227l20.519,4.617z"/>                 </canvas>             </border>         </controltemplate>     </usercontrol.template> </usercontrol>

i reference usercontrol , use in listview. object listview binding has property named status. when status set "running", i'd change style. when run it, button hidden know status property notifying properly. svg:busyindicator control remains unchanged.

<usercontrol x:class="foo.views.screens.collectionresultsview"                  automationproperties.automationid="collectionresultsview"                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                  xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"                    mc:ignorable="d"                  xmlns:d="http://schemas.microsoft.com/expression/blend/2008"                  xmlns:svg="clr-namespace:foo.client.ui.svgs;assembly=foo.client.ui"                   d:designwidth="700">     <listview itemssource="{binding targetstatusview}">         <stackpanel>             <button>                 <textblock text="x"></textblock>                 <button.style>                     <style targettype="button">                         <setter property="visibility" value="visible" />                         <style.triggers>                             <datatrigger binding="{binding status}" value="running">                                 <setter property="visibility"  value="hidden" />                             </datatrigger>                         </style.triggers>                     </style>                 </button.style>             </button>             <svg:busyindicator width="25" height="25">                 <svg:busyindicator.style>                     <style targettype="svg:busyindicator">                         <setter property="visibility" value="visible" />                         <style.triggers>                             <datatrigger binding="{binding status}" value="running">                                 <setter property="visibility" value="hidden"/>                             </datatrigger>                         </style.triggers>                     </style>                 </usercontrol.style>             </svg:busyindicator>         </stackpanel>     </listview> </usercontrol>

i tried change targettype usercontrol didn't work either.

<svg:busyindicator width="25" height="25">     <usercontrol.style>         <style targettype="usercontrol">             <setter property="visibility" value="visible" />             <style.triggers>                 <datatrigger binding="{binding status}" value="running">                     <setter property="visibility" value="hidden"/>                     <setter property="foreground" value="white" />                 </datatrigger>             </style.triggers>         </style>     </usercontrol.style> </svg:busyindicator>

setting <svg:busyindicator width="25" height="25" visibility="hidden"> work if add <setter property="visibility" value="hidden" /> style, above <style.triggers>, not work.

i tried other properties opacity , height without success.

what missing?

the issue way defined busyindicator control. because datacontext set {binding relativesource={relativesource self}}. this, when used in listview, context control , not data bound listview. binding="{binding status}" did work because busyindicator usercontrol doesn't have status prooperty.

we updated control below , worked.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
