winforms - WindowsFormHost items in a WPF ListBox - Z-Order -

-

i have been end of web , , can't seem find solution z-ordering windowsformshost issue. issue specific rendering listbox items windowsformshost wrapped winform controls. when rendered items displayed outside bounds of listbox -- makes entire screen horrible.

i attaching quick code sample. have options? need rethink layout?

    <window x:class="wfh_zorderissue.window1"   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"   xmlns:wf="clr-namespace:system.windows.forms;assembly=system.windows.forms"   xmlns:wfi="clr-namespace:system.windows.forms.integration;assembly=windowsformsintegration"   title="wfh listbox zorder" height="300" width="600">  <grid>   <listbox background="lightblue" horizontalalignment="left" itemssource="{binding}" maxwidth="400" borderthickness="0"       scrollviewer.verticalscrollbarvisibility="hidden" scrollviewer.cancontentscroll="false"       scrollviewer.horizontalscrollbarvisibility="auto"      selectionmode="extended" x:name="lstdisplays"       >    <listbox.itemtemplate>     <datatemplate>      <scrollviewer x:name="viewer" verticalscrollbarvisibility="hidden" >       <wfi:windowsformshost margin="20,0" x:name="host">        <wf:button text="windowformshost - ugly" />       </wfi:windowsformshost>      </scrollviewer>     </datatemplate>    </listbox.itemtemplate>    <listbox.itemspanel>     <itemspaneltemplate>      <stackpanel orientation="horizontal" />     </itemspaneltemplate>    </listbox.itemspanel>   </listbox>  </grid> </window>

and codebehind:

    /// <summary>  /// interaction logic window1.xaml  /// </summary>  public partial class window1 : window  {   public window1()   {    initializecomponent();    this.datacontext = system.linq.enumerable.range(0, 30);   }  }

please :)

this known airspace issue. winforms render above wpf since both use different rendering technologies. there few solutions around not straight forward.

have @ this blog entry or here might able working.

if doesn't work suggest not place winforms anywhere lower top level (i.e. on window) , make sure not fancy layouts.
