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.
