but editing template foreground color change not working.

you can using style,

   <window.resources>         <style x:key="buttoncancel" targettype="{x:type button}">             <setter property="foreground">                 <setter.value>                     <lineargradientbrush endpoint="0.5,1" startpoint="0.5,0">                         <gradientstop color="red" offset="0"/>                                           </lineargradientbrush>                 </setter.value>             </setter>             <style.triggers>                 <trigger property ="ismouseover" value="true">                     <setter property= "foreground"  >                         <setter.value>                             <lineargradientbrush endpoint="0.5,1" startpoint="0.5,0">                                 <gradientstop color="green" offset="0"/>                             </lineargradientbrush>                         </setter.value>                     </setter>                 </trigger>             </style.triggers>         </style>     </window.resources>     <grid>         <button style="{dynamicresource buttoncancel}"   fontsize="18" fontweight="bold" width="144" name="btncancel"                 horizontalalignment="right" grid.row="1"  grid.column="1" margin="0,73.5,0,55.5"> test         </button>     </grid>
