wpf - Giving a button in a textbox functionality, without using a custom control but overiding the textbox template -

i implemented button textbox overriding template code below:

<style x:key="{x:type textbox}" targettype="{x:type textboxbase}">    <setter property="template">         <setter.value>             <controltemplate targettype="{x:type textboxbase}">                  <border name="border"                     cornerradius="2"                      padding="2"                     background="{staticresource windowbackgroundbrush}"                     borderbrush="{staticresource solidborderbrush}"                     borderthickness="1">                      <grid x:name="layoutgrid">                         <grid.columndefinitions>                             <columndefinition width="*" />                             <columndefinition width="auto" />                             <columndefinition width="auto" />                         </grid.columndefinitions>                          <scrollviewer x:name="part_contenthost" grid.column="0" />                           <button x:name="xbutton"                                 grid.column="2"                                 width="25"                                 height="25"                                 content="x"                                 visibility="visible"                                 borderbrush="transparent"                                 command="{binding  buttonclick}" />                     </grid>                  </border>              </controltemplate>         </setter.value>     </setter> </style> 

the button should delete content in textbox when hit. use command "command="{binding buttonclick}""

can binding done without creating custom control , library ? or how can binding or functionality done ?

i using mvvm pattern there way example use viewmodel , create property bind ?

for bindings in style use attachedcommandbehaviors "acb"

http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/

i use detecting clicks on items in style want detect clicks on. haven't used buttons think should work well.

i binding style's ancestor who's type user control may need changed application.

you'll need add xmlns:acb namespace in xaml see link details.
