silverlight - Item Template in the ItemPresenter -

in template itempresenter defines host panel items. possible define itemtemplate?

<controltemplate x:key="itemscontroltemplate" targettype="itemscontrol">     <grid>         <grid.rowdefinitions>             <rowdefinition height="*"/>         </grid.rowdefinitions>         <scrollviewer>             <itemspresenter width="{templatebinding width}" height="{templatebinding height}"/>         </scrollviewer>     </grid> </controltemplate> 

to go further, i've created class:

public class itemscontrolextended : itemscontrol {     public itemscontrolextended()     {         defaultstylekey = typeof(itemscontrolextended);     } } 

and create dependency property "itemsmargin". after i've done i'm supposed bind item "margin" property "itemsmargin". how possible implement?

getcontainerforitemoverride ? preparecontainerforitemoverride ? onapplytemplate ?

you can't define itemtemplate controltemplate control whole.

instead create style includes control template , the other templates required:-

 <style x:key="itemscontrolstyle" targettype="itemscontrol>    <setter property="template">       <setter.value>           <controltemplate targettype="itemscontrol">               <!-- template above -->           </controltemplate>       </setter.value>    </setter>     <setter property="itemspanel">       <setter.value>           <itemspaneltemplate>               <!-- alternative stackpanel if desired -->           </itemspaneltemplate>       </setter.value>    </setter>      <setter property="itemtemplate">       <setter.value>           <dataltemplate>               <!-- item template wanted -->           </datatemplate>       </setter.value>    </setter>  </style> 

now can style itemscontrol:-

<itemscontrol style="{staticresource itemscontrolstyle}">
