wpf - RadioButton change background color when checked -


i want override radiobutton style togglebutton 1 

<radiobutton content="point">     <radiobutton.template>         <controltemplate>             <togglebutton ischecked="{binding ischecked, relativesource={relativesource templatedparent}, mode=twoway}"                           content="{binding content, relativesource={relativesource templatedparent}, mode=twoway}"/>             <controltemplate.triggers>                 <trigger property="ischecked" value="true">                     <setter property="background" value="red"/>                 </trigger>             </controltemplate.triggers>         </controltemplate>     </radiobutton.template> </radiobutton>

i need change background color of button when it's checked. tried trigger it's not working.

the solution not simple one. issue related fact togglebutton has default background when checked, , 1 has removed, before changing different one.

take @ topic: changing background color of togglebutton when checked

here code should want (used topic reference remove blue highlight on buttons wpf):

 <radiobutton content="point">         <radiobutton.template>             <controltemplate>                 <togglebutton ischecked="{binding ischecked, relativesource={relativesource templatedparent}, mode=twoway}"                               content="{binding content, relativesource={relativesource templatedparent}, mode=twoway}" background="transparent">                     <togglebutton.style>                         <style targettype="togglebutton">                             <setter property="overridesdefaultstyle" value="true"/>                             <setter property="margin" value="5"/>                             <setter property="template">                                 <setter.value>                                     <controltemplate targettype="togglebutton">                                         <border name="border"                                                  borderthickness="1"                                                 padding="4,2"                                                  borderbrush="darkgray"                                                  cornerradius="3"                                                  background="{templatebinding background}">                                             <contentpresenter horizontalalignment="center" verticalalignment="center" />                                         </border>                                         <controltemplate.triggers>                                             <trigger property="ismouseover" value="true">                                                 <setter targetname="border" property="borderbrush" value="black" />                                             </trigger>                                             <trigger property="ischecked" value="true">                                                 <setter targetname="border" property="background" value="red"/>                                             </trigger>                                         </controltemplate.triggers>                                     </controltemplate>                                 </setter.value>                             </setter>                         </style>                     </togglebutton.style>                 </togglebutton>             </controltemplate>         </radiobutton.template>     </radiobutton>
