c# - how to trigger visibility change to child controls with a trigger -


i have databound listbox thet generates items in datatemplate of type wrappanel other controls within it. have behavior to, when change visibility affect differently controls within wrappanel

    <wrappanel orientation="horizontal" tag="{binding .}" horizontalalignment="stretch" visibility="{binding editmode, converter={staticresource visibilityconverter}}">                     <label width="150" content="{binding path=avaiableattribute.text}" name="lblname"/>                     <label width="150"                             content="{binding path=informationitem.itemstring, mode=twoway,  updatesourcetrigger=propertychanged}"                             initialized="label_initialized"                             name="lbltext" />                     <contentpresenter minwidth="200" maxheight="200" content="{binding ., converter={staticresource informationitemconverter}, mode=twoway}" horizontalalignment="stretch"                                       name="cpvalue"                                       initialized="contentpresenter_initialized"/>                      <wrappanel.style>                         <style  targettype="{x:type wrappanel}">                             <style.triggers>                                 <trigger property="visibility" value="visible" >                                     <trigger.setters>                                         <setter targetname="lbltext" property="visibility" value="collapsed" />                                         <setter targetname="cpvalue" property="visibility" value="visible" />                                     </trigger.setters>                                 </trigger>                             </style.triggers>                         </style>                     </wrappanel.style>     </wrappanel> 

i following build error

the property 'targetname' not represent valid target 'setter' because element

when using setter, targetname applies elements in template. means trigger has exist in datatemplate or controltemplate. easiest way want create own ivalueconverter inverse of booleantovisibilityconverter (ie return visibility.collapsed when value true).
