wpf - Set ContentTemplate for ListViewItem from Custom View -


i create custom view listview control.

public class customview: view{ //...         public datatemplate itemtemplate { get; set; } //... }   <customview x:key="custom">     <customview.itemtemplate>         <datatemplate>         </datatemplate>     </customview.itemtemplate> </customview> 

in style listviewitem bind datatemplate customview.itemtemplate on contenttemplate.

<style x:key="{componentresourcekey typeintargetassembly={x:type customview}, resourceid=customviewitem}"        targettype="{x:type listviewitem}"        basedon="{staticresource {x:type listboxitem}}">      <setter property="contenttemplate"             value="{binding path=view.itemtemplate,                                  relativesource={relativesource findancestor, ancestortype={x:type listview}}}" />      <setter property="template">         <setter.value>             <controltemplate targettype="{x:type listboxitem}">                 <border x:name="itemborder">                     <contentpresenter />                 </border>         </setter.value>     </setter> </style>   <style x:key="{componentresourcekey typeintargetassembly={x:type customview}, resourceid=customview}"        targettype="{x:type listview}"        basedon="{staticresource {x:type listbox}}">  </style> 

view works in output window in vs error:

cannot find source binding reference 'relativesource findancestor, ancestortype='system.windows.controls.listview', ancestorlevel='1''. bindingexpression:path=view.itemtemplate; dataitem=null; target element 'listviewitem' (name=''); target property 'contenttemplate' (type 'datatemplate')

public class customlistview : listview {

static customlistview()   { 

defaultstylekeyproperty.overridemetadata(typeof(customlistview), new frameworkpropertymetadata(typeof(customlistview)));

}  protected override dependencyobject getcontainerforitemoverride() {     return new customlistviewitem(); } 

}
