c# 4.0 - wpf Treeview CheckBox Item ForeGround Color cannot Change when it is disabled? -

-

this xaml style treeview checkbox item. i'm using syncfusion treeview.

<style x:key="contractlistitemcontainerstyle" targettype="{x:type syncfusion:treeviewitemadv}">     <setter property="isexpanded" value="true" />     <setter property="isselected" value="{binding isinitiallyselected, mode=onetime}" />     <setter property="keyboardnavigation.acceptsreturn" value="true" />     <setter property="iseditable" value="false" />      <setter property="isenabled" value="{binding enable}" />     <setter property="foreground" value="red" />     <style.triggers>         <trigger property="isenabled" value="true">             <setter property="foreground" value="green" />         </trigger>         <trigger property="isenabled" value="false">             <setter property="foreground" value="red" />         </trigger>     </style.triggers> </style>  <hierarchicaldatatemplate x:key="selectedcontractsdatatemplate" itemssource="{binding children}" >     <stackpanel orientation="horizontal">         <checkbox margin="2,0,2,0"              focusable="false"              ischecked="{binding content.ischecked}"              verticalalignment="center"  />         <contentpresenter content="{binding}" margin="2,0"  />     </stackpanel> </hierarchicaldatatemplate>

if set enable false viewmodel, color doesn't change red if set true, changes green. why? pelase advise.

the code should work, see/try this:

<stackpanel>     <checkbox name="chk" content="check this...">         <checkbox.style>             <style>                 <setter property="checkbox.foreground" value="red" />                 <style.triggers>                     <trigger property="checkbox.isenabled" value="true">                         <setter property="checkbox.foreground" value="green" />                     </trigger>                     <trigger property="checkbox.isenabled" value="false">                         <setter property="checkbox.foreground" value="red" />                     </trigger>                 </style.triggers>             </style>         </checkbox.style>     </checkbox>     <button content="press" click="button_click"/> </stackpanel>

probably wrong binding?
