<listbox name="box" scrollviewer.horizontalscrollbarvisibility="disabled" background="transparent" borderthickness="0">             <listbox.itemcontainerstyle>                 <style targettype="listboxitem">                     <setter property="template">                         <setter.value>                             <controltemplate>                                 <stackpanel orientation="horizontal" margin="40,2,0,2">                                     <textblock text="{binding label}" minwidth="20" />                                     <textbox  tabindex="{binding index, mode=oneway}" text="{binding information, mode=twoway}"/>                                 </stackpanel>                             </controltemplate>                         </setter.value>                     </setter>                 </style>             </listbox.itemcontainerstyle>         </listbox>  namespace silverlightapplication1 {     public partial class mainpage : usercontrol     {         public mainpage()         {             initializecomponent();              var model = new list<model>()             {                 new model() {index = 1, label = "1"},                 new model() {index = 2, label = "2"},                 new model() {index = 3, label = "3"},                 new model() {index = 4, label = "4"}             };              box.itemssource = model;           }     }       public class model     {         public int index { get; set; }         public string label { get; set; }         public string information { get; set; }     } }

you'll need specify in style how want tabs work. shouldn't need bind tabindex, unless want change order tab works in. think should work similar trying do:

<listbox name="box"          scrollviewer.horizontalscrollbarvisibility="disabled"          background="transparent"          borderthickness="0">     <listbox.itemcontainerstyle>         <style targettype="listboxitem">             <setter property="template">                 <setter.value>                     <controltemplate>                         <stackpanel orientation="horizontal"                                     margin="40,2,0,2">                             <textblock text="{binding label}"                                        minwidth="20" />                             <textbox text="{binding information, mode=twoway}" />                         </stackpanel>                     </controltemplate>                 </setter.value>             </setter>             <setter property="istabstop"                     value="false" />         </style>     </listbox.itemcontainerstyle>     <listbox.style>         <style targettype="listbox">             <setter property="tabnavigation"                     value="cycle" />         </style>     </listbox.style> </listbox>
