Copy Functionality on a TreeView

In the project I'm working on, I'm using a treeview to display a dump of some xml file. I wanted to be able to add the copy functionality so that users could copy the information and paste it somewhere useful. Because TreeViewItem s do not have this functionality by default I wrote the following code. Hopefully it will be of some use to you.

Call this function on every TreeViewItem you want the copy command to work on

private void AddCopyCommand(ref TreeViewItem tvi)
{
      CommandBinding copyCmdBinding = new CommandBinding();
      copyCmdBinding.Command = ApplicationCommands.Copy;
      copyCmdBinding.Executed += copyCmdBinding_Executed;
      copyCmdBinding.CanExecute += copyCmdBinding_CanExecute;
      tvi.CommandBindings.Add(copyCmdBinding);
}

Alternatively you could do this in xaml with:

<TreeViewItem>
<TreeViewItem.Commandbindings>
<CommandBinding Command="ApplicationCommands.Copy"
     Executed="copyCmdBinding_Executed"
     CanExecute="copyCmdBinding_CanExecute"/>
</TreeViewItem.CommandBindings
</TreeViewItem>

Then you have to write the functions to check for execution and actually execute:

private void copyCmdBinding_Executed (object sender, ExecutedRoutedEventArgs e) {
      // Set text to clip board
      TreeViewItem tvi = (TreeViewItem)sender;
      Clipboard.SetText((String)tvi.Header);
}

private void copyCmdBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e)
{
      //Check for text
      TreeViewItem tvi = (TreeViewItem)sender;
      if (tvi.Header != null)
      {
            e.CanExecute = true;
      }
      else
      {
            e.CanExecute = false;
      }
}


Note: This should work on any WPF Control, not just the TreeViewItem.
