c# - How to use ElementName binding from resource? -

i've added menuflyout button in itemscontrol.itemtemplate. able bind current item commandparameter. want bind command menuflyoutitem. in codebehind :

layoutroot.datacontext = this; 

so if bind layoutroot bind current usercontrol. following binding not working:

command="{binding activateprofilecommand, elementname=layoutroot}" 

it gives me not errors in output it's not working. here's full example:

<controls:headerdecorator x:uid="accountsheader" text="accounts" x:name="layoutroot" name="layoutroot">     <controls:headerdecorator.resources>         <menuflyout x:key="accountmenuflyout">             <menuflyoutitem text="activate" name="activate"                          command="{binding activateprofilecommand, elementname=layoutroot}"                         commandparameter="{binding}" />         </menuflyout>     </controls:headerdecorator.resources>     <stackpanel orientation="vertical">         <itemscontrol itemssource="{binding settings.profiles}" >             <itemscontrol.itemtemplate>                 <datatemplate>                     <hyperlinkbutton content="{binding}"  flyoutbase.attachedflyout="{staticresource accountmenuflyout}" >                         <i:interaction.behaviors>                             <ic:showflyoutbehavior />                         </i:interaction.behaviors>                     </hyperlinkbutton>                 </datatemplate>             </itemscontrol.itemtemplate>         </itemscontrol>     </stackpanel> </controls:headerdecorator>
