wpf - Custom DependencyProperty on Style.Trigger -

for usercontrol declared dependencyproperty :

        public static readonly dependencyproperty deselectedpresentationmodeproperty =         dependencyproperty.register(         "deselectedpresentationmode",         typeof(int),         typeof(myusercontrol),         new frameworkpropertymetadata(1,frameworkpropertymetadataoptions.affectsrender | frameworkpropertymetadataoptions.bindstwowaybydefault));      public static readonly dependencyproperty selectedpresentationmodeproperty =         dependencyproperty.register(         "selectedpresentationmode",         typeof(int),         typeof(myusercontrol),         new frameworkpropertymetadata(1, frameworkpropertymetadataoptions.affectsrender | frameworkpropertymetadataoptions.bindstwowaybydefault)); 

now want use these properties within multitrigger:

    <style targettype="{x:type listboxitem}" basedon="{staticresource {x:type listboxitem}}" x:key="myusercontrolitemstyle">         <style.triggers>             <multitrigger>                 <multitrigger.conditions>                     <condition property="isselected" value="false" />                     <condition property="gui:myusercontrol.deselectedpresentationmode" value="0" />                 </multitrigger.conditions>                 <multitrigger.setters>                     <setter property="contenttemplate" value="{staticresource presentationmodeicononly}" />                 </multitrigger.setters>             </multitrigger>             <multitrigger>                 <multitrigger.conditions>                     <condition property="isselected" value="false" />                     <condition property="gui:myusercontrol.deselectedpresentationmode" value="1" />                 </multitrigger.conditions>                 <multitrigger.setters>                     <setter property="contenttemplate" value="{staticresource presentationmodesimple}" />                 </multitrigger.setters>             </multitrigger>             <multitrigger>                 <multitrigger.conditions>                     <condition property="isselected" value="true" />                     <condition property="gui:myusercontrol.selectedpresentationmode" value="0" />                 </multitrigger.conditions>                 <multitrigger.setters>                     <setter property="contenttemplate" value="{staticresource presentationmodeextended}" />                 </multitrigger.setters>             </multitrigger>             <multitrigger>                 <multitrigger.conditions>                     <condition property="isselected" value="true" />                     <condition property="gui:myusercontrol.selectedpresentationmode" value="1" />                 </multitrigger.conditions>                 <multitrigger.setters>                     <setter property="contenttemplate" value="{staticresource presentationmodeicononly}" />                 </multitrigger.setters>             </multitrigger>         </style.triggers>     </style>     ...     ...     <listbox ... itemcontainerstyle="{staticresource myusercontrolitemstyle}"/> 

but if use myusercontrol project, there no reaction if change dependencyproperty. whether use xaml e.g:

<window  ... x:class="wpfcontrolstester.mainwindow"  title="mainwindow"> <grid>     <gui:myusercontrol name="test"/>     <slider minimum="0" maximum="1" value="{binding selectedpresentationmode, elementname=test}" />     <slider minimum="0" maximum="1" value="{binding deselectedpresentationmode, elementname=test}" /> </grid> 

or if use kind of manipulation value this.test.deselectedpresentationmode = 0; on event or smth else.

i used wpf inspector "debug" triggers, , both properties had default value (1). mistake or should add update triggers?

edit : changed false "mycontrol "myusercontrol"

you can try multidatatrigger instead in order property changes:

<style.triggers>                 <multidatatrigger>                         <multidatatrigger.conditions>                         <condition binding="{binding isselected, relativesource={relativesource self}}" value="false" />                         <condition binding="{binding deselectedpresentationmode, relativesource={relativesource ancestortype={x:type myusercontrol}}}" value="0" />                         </multidatatrigger.conditions>                             <multidatatrigger.setters>                         <setter property="contenttemplate" value="{staticresource presentationmodeicononly}" />                         </multidatatrigger.setters>                 </multidatatrigger>             </style.triggers>
