Make WPF textbox as cut, copy and paste restricted

Question

How can I make a WPF textbox cut, copy and paste restricted?

Answer 1

The commandName method will not work on a System with Japanese OS as the commandName=="Paste" comparision will fail. I tried the following approach and it worked for me. Also I do not need to disable the context menu manually.

In the XaML file:

In the code behind:

private void CommandBinding_CanExecutePaste(object sender, CanExecuteRoutedEventArgs e)
{
    e.CanExecute = false;
    e.Handled = true;
}
