wpf - C+Ctrl KeyBinding is not causing copying to happen -

i have set listbox so:

<listbox itemssource="{binding logs, mode=oneway}" x:name="loglistview">     <listbox.itemtemplate>         <datatemplate>             <textblock text="{binding path=.}">                 <textblock.inputbindings>                     <keybinding key="c"                                 modifiers="ctrl"                                 command="copy"/>                 </textblock.inputbindings>                 <textblock.commandbindings>                     <commandbinding command="copy"                                     executed="keycopylog_executed"                                     canexecute="copylog_canexecute"/>                 </textblock.commandbindings>                 <textblock.contextmenu>                     <contextmenu>                         <menuitem command="copy">                             <menuitem.commandbindings>                                 <commandbinding command="copy"                                                 executed="menucopylog_executed"                                                 canexecute="copylog_canexecute"/>                             </menuitem.commandbindings>                         </menuitem>                     </contextmenu>                 </textblock.contextmenu>             </textblock>         </datatemplate>     </listbox.itemtemplate> </listbox> 

as can see, in template, each textblock has context menu allows user copy text. works.

also in textblock there keybinding ctrl+c , commandbinding copy. when press ctrl+c method keycopylog_executed not executed. i've checked debugger.

how should binding keys textblock?

there couple of problems here.

first of all, keybindings work if focused element located inside element keybindings defined. in case have listboxitem focused, keybindings defined on child element - textblock. so, defining keybindings on textblock not work in case, since textblock cannot receive focus.

second of all, need know copy, need pass selected log item parameter copy command.

furthermore, if define contextmenu on textblock element opened if right-click on textblock. if click on other part of list item, not open. so, need define contextmenu on list box item itself.

considering of that, believe trying can done in following way:

<listbox itemssource="{binding logs, mode=oneway}"          x:name="loglistview"          issynchronizedwithcurrentitem="true">     <listbox.inputbindings>         <keybinding key="c"                     modifiers="ctrl"                     command="copy"                     commandparameter="{binding logs/}" />     </listbox.inputbindings>      <listbox.commandbindings>         <commandbinding command="copy"                         executed="copylogexecuted"                         canexecute="canexecutecopylog" />     </listbox.commandbindings>      <listbox.itemcontainerstyle>         <style targettype="{x:type listboxitem}">             <setter property="contextmenu">                 <setter.value>                     <contextmenu>                         <menuitem command="copy"                                   commandparameter="{binding}" />                     </contextmenu>                 </setter.value>             </setter>         </style>     </listbox.itemcontainerstyle>      <listbox.itemtemplate>         <datatemplate>             <textblock text="{binding}" />         </datatemplate>     </listbox.itemtemplate> </listbox> 

here define keybinding on listbox , specify commandparameter selected list box item (log entry).

commandbinding defined @ listbox level , single binding both right click menu , keyboard shortcut.

the contextmenu define in style listboxitem , bind commandparameter data item represented listboxitem (log entry).

the datatemplate declares textblock binding current data item.

and finally, there 1 handler copy command in code-behind:

private void copylogexecuted(object sender, executedroutedeventargs e) {     var logitem = e.parameter;      // copy log item clipboard }  private void canexecutecopylog(object sender, canexecuteroutedeventargs e) {     e.canexecute = true; }
