c# - Extending a Separator (Deriving from) -


i have implement custom separator, few custom properties (the main 1 header):

public class headeredseparator : separator {     //more properties here... headerforeground , separatorheight.     public static readonly dependencyproperty headerproperty = dependencyproperty.register("header", typeof(string), typeof(headeredseparator));      [bindable(true), category("common")]     public string header     {         { return (string)getvalue(headerproperty); }         set { setvalue(headerproperty, value); }     }      static headeredseparator()     {         defaultstylekeyproperty.overridemetadata(typeof(headeredseparator), new frameworkpropertymetadata(typeof(headeredseparator)));     } }

and style (inside themes\generic.xaml):

<style x:key="{x:static menuitem.separatorstylekey}" targettype="{x:type c:headeredseparator}">     <setter property="isenabled" value="false"/>     <setter property="height" value="auto"/>     <setter property="separatorheight" value="1"/>     <setter property="foreground" value="#ffe0e3e6"/>     <setter property="headerforeground" value="#ff202326"/>     <setter property="fontsize" value="12"/>     <setter property="verticalcontentalignment" value="center"/>     <setter property="horizontalcontentalignment" value="stretch"/>     <setter property="horizontalalignment" value="stretch"/>      <setter property="template">         <setter.value>             <controltemplate targettype="{x:type c:headeredseparator}">                 <grid margin="0,4" horizontalalignment="stretch">                     <grid.columndefinitions>                         <columndefinition width="auto"/>                         <columndefinition/>                     </grid.columndefinitions>                      <textblock grid.column="0" text="{templatebinding header}" fontsize="{templatebinding fontsize}"                                 foreground="{templatebinding headerforeground}"/>                      <rectangle grid.column="1" height="{templatebinding separatorheight}" fill="{templatebinding foreground}"                                verticalalignment="{templatebinding verticalcontentalignment}"                                 horizontalalignment="{templatebinding horizontalcontentalignment}"                                stretch="fill"/>                 </grid>             </controltemplate>         </setter.value>     </setter> </style>

(edit) usage:

<c:headeredseparator header="itens"/>

this separator supposed display header while being used inside menu. that's why i'm using key attribute, reason, isn't working (the default style being loaded). guys know why?

c# - Check Keyboard Input Winforms -
