xaml - Style inheritance - how to refine a custom default style? -

-

in winrt / uwp app (the problem occurs on both platforms), can define style applies instances of control, omitting x:key attribute, e.g.:

<style targettype="button">     <setter property="width" value="400"/> </style>

now, i'd apply properties buttons in addition default style:

<style targettype="button" x:key="tallbuttonstyle" basedon="...">     <setter property="height" value="100"/> </style>

the problem is: fill in basedon attribute, style inherits default style defined above?

in wpf, following:

<style targettype="button" x:key="..." basedon="{staticresource  {x:type button}}">

however, x:type not available on winrt / uwp. this answer suggests, need assign x:key default style in order able inherit it:

<style targettype="button" x:key="widebuttonstyle">     <setter property="width" value="400"/> </style> <style targettype="button" x:key="tallbuttonstyle" basedon="{staticresource button}">     <setter property="height" value="100"/> </style>

however, in case widebuttonstyle not used default more, , i'd need apply style="{staticresource widebuttonstyle}" buttons manually, seams unneessary overhead me.

is there way, either

  1. set style's basedon attribute point respective control's default style, or
  2. set style contains x:key attribute used standard controls of given type?

btw, this related topic not answer question, shows how override default style defined in winrt / uwp platform, not custom-made default style.

you can give default style x:key, make empty style without x:key based on style. style apply instances of control "reference" first style. can create additional styles based on first style x:key. not elegant solution think cannot better.
