windows runtime - Edit TextBox's Header property inside Style -


how customize textbox's header property inside styles winrt.

i want change header's fontsize & foreground property inside style.

i tried this:

<style x:name="valuetextboxportraitstyle" targettype="textbox" basedon="{staticresource valuetextboxstyle}">     <setter property="borderthickness" value="6"/>     <setter property="fontsize" value="18"/>     <setter property="margin" value="0,0,0,10"/>     <setter property="header">         <setter.value>             <headertemplate>                 <datatemplate>                     <textblock text="{binding}" fontsize="10" foreground="green"/>                 </datatemplate>             </headertemplate>         </setter.value>     </setter> </style>

but gives error.
