Question

What is the best way to add ‘copy to clipboard’ functionality to a ListView control in WPF?

I tried adding an ApplicationCommands.Copy to either the ListView ContextMenu or the ListViewItem ContextMenu, but the command remains disabled.

Thanks, Peter

Here is an xaml sample of one of my attempts…

 <Window.Resources>     <ContextMenu x:Key='SharedInstanceContextMenu' x:Shared='True'>         <MenuItem Header='Copy' Command='ApplicationCommands.Copy'/>                 </ContextMenu>  </Window.Resources>   <ListBox Margin='12,233,225,68' Name='listBox1' >         <ListBox.ItemTemplate>             <DataTemplate>                 <TextBlock Text='{Binding Path=UpToSourceCategoryByCategoryId.Category}' ContextMenu='{DynamicResource ResourceKey=SharedInstanceContextMenu}'/>             </DataTemplate>         </ListBox.ItemTemplate>  </ListBox> 

How should I set the CommandTarget in this case?

Thanks,Peter

It looks like you need a CommandBinding.

Here is how I would probably go about doing what you trying to do.

<Window.CommandBindings>     <CommandBinding         Command='ApplicationCommands.Copy'         Executed='CopyCommandHandler'         CanExecute='CanCopyExecuteHandler' /> </Window.CommandBindings>  <Window.Resources>     <ContextMenu x:Key='SharedInstanceContextMenu'>         <MenuItem Header='Copy' Command='ApplicationCommands.Copy'/>     </ContextMenu>      <Style x:Key='MyItemContainerStyle' TargetType='{x:Type ListBoxItem}'>         <Setter Property='ContextMenu' Value='{StaticResource SharedInstanceContextMenu}' />     </Style> </Window.Resources>  <ListBox ItemContainerStyle='{StaticResource MyItemContainerStyle}'>     <ListBoxItem>One</ListBoxItem>     <ListBoxItem>Two</ListBoxItem>     <ListBoxItem>Three</ListBoxItem>     <ListBoxItem>Four</ListBoxItem> </ListBox>
