xaml - Change property of "super/base" style wpf -


i creating base style. using inheritance implement base style. know how add properties on derived class don't know how change property. let me give example:

let have base style:

        <!-- srollviewer scrollbar repeat buttons (at each end) -->     <style x:key="scrollbarlinebutton" targettype="{x:type repeatbutton}">         <setter property="snapstodevicepixels" value="true"/>         <setter property="overridesdefaultstyle" value="true"/>         <setter property="focusable" value="false"/>         <setter property="template">             <setter.value>                 <controltemplate targettype="{x:type repeatbutton}">                     <border                         name="border"                         margin="1"                         cornerradius="2"                         background="whitesmoke"                                   borderthickness="1">                         <image stretch="uniform" source="/filespro;component/images/scrollarrow.png" height="40" verticalalignment="center" horizontalalignment="center" width="52" >                             <image.rendertransform>                                 <transformgroup>                                     <scaletransform scaley="-1" />                                     <translatetransform y="40"/>                                     <skewtransform/>                                     <rotatetransform/>                                     <translatetransform/>                                 </transformgroup>                             </image.rendertransform>                         </image>                         <!--                         <path                             horizontalalignment="center"                             verticalalignment="center"                             fill="{staticresource glyphbrush}"                             data="{binding path=content,                                 relativesource={relativesource templatedparent}}" >                         </path>                         -->                     </border>                 </controltemplate>             </setter.value>         </setter>      </style>

i create new style has same properties scrollbarlinebutton image transfrom scaley=1 instead of -1.

when do:

        <style x:key="scrollbarlinebuttonverticalup" basedon="{staticresource scrollbarlinebutton}" targettype="{x:type repeatbutton}">         <setter property="template">             <setter.value>                 <controltemplate targettype="{x:type repeatbutton}">                     <border>                                                     <image stretch="uniform" source="/filespro;component/images/scrollarrow.png" height="40" verticalalignment="center" horizontalalignment="center" width="52" >                             <image.rendertransform>                                 <transformgroup>                                     <scaletransform scaley="1" />                                      ....                                      ...

border no longer has base style margin, background color etc.. how inherit style , change 1 property. know can copy paste change lot , convenient if change in 1 place changes in other places.

you can create dynamicresource reference this, here's example:

<stackpanel>     <stackpanel.resources>         <style x:key="buttonstylea" targettype="{x:type button}">             <style.resources>                 <solidcolorbrush x:key="textbrush" color="yellow" />             </style.resources>             <setter property="template">                 <setter.value>                     <controltemplate targettype="{x:type button}">                         <border cornerradius="10" borderthickness="1" borderbrush="red">                             <contentpresenter textelement.foreground="{dynamicresource textbrush}"/>                         </border>                     </controltemplate>                 </setter.value>             </setter>         </style>          <style x:key="buttonstyleb" targettype="{x:type button}" basedon="{staticresource buttonstylea}">             <style.resources>                 <solidcolorbrush x:key="textbrush" color="blue" />             </style.resources>         </style>     </stackpanel.resources>     <button style="{staticresource buttonstylea}" content="lorem ipsum" />     <button style="{staticresource buttonstyleb}" content="lorem ipsum" /> </stackpanel>

in styleb textbrush overridden causes template change since references resource.
