wpf - <Image> source not working on binding -

i trying bind listbox via itemstemplate collection of custom "document" objects having issue while trying bind image document.imageresourcepath property. here markup

<listbox name="lbdocuments">             <listbox.itemtemplate>                 <datatemplate>                     <stackpanel>                         <image source="{binding path=imageresourcepath}"                                    margin="5,0,5,0"/>                     </stackpanel>                 </datatemplate>             </listbox.itemtemplate>                 </listbox> 

this load event form has listbox.

    private void window_loaded_1(object sender, routedeventargs e)     {          list<objects.document> docs = objects.document.fetchdocuments();         lbdocuments.itemssource = docs;     } 

my document class holds string resource image located in resources folder depending on document extension.

e.g. (this part of case statement within document class)

    case cache.documenttype.pdf:     this.imageresourcepath = "/juvenileorganizationemail;component/resources/pdf_icon.jpg";     break; 

when window loads absolutely nothing in listbox when bound 23 document types. doing wrong?

use observablecollection instead of list, , make reference "class level" window.

observablecollection<objects.document> _docs;  

make sure datacontext set in window's ctor.

public window() {   _docs = new observablecollection<objects.document>(objects.document.fetchdocuments());    this.datacontext = this; } 

then, can update window loaded event:

   private void window_loaded_1(object sender, routedeventargs e)     {         lbdocuments.itemssource = _docs;     } 

or, alternative solution, binding itemssource of listbox directly public property of collection. assuming ctor (above) still used.

<listbox name="lbdocuments" itemssource={binding docs}>             <listbox.itemtemplate>                 <datatemplate>                     <stackpanel>                         <image source="{binding path=imageresourcepath}" margin="5,0,5,0"/>                     </stackpanel>                 </datatemplate>             </listbox.itemtemplate>                 </listbox> 

in window.cpp file (though, separate viewmodel class may recommended if doing mvvm)

  public observablecollection<objects.document> docs    {      { return _docs; }   }
