Disable CTRL + P in WPF DocumentViewer

Question

I am working on a new presentation component for one of our applications. I am creating a WPF user control that has only a DocumentViewer in it and places this CC in a Windows Forms application with ElementHost. I am using Visual Studio 2008 with C #.

I configured everything through XAML to give it an appearance that integrates it into our application, but one thing remains ...

If you press CTRL + P, the print dialog will still appear. I will completely lose how to disable this feature. Using this CC allows users to download and view the manuals for the systems installed on this site, but we do not want them to accidentally print them (100 pages).

Answer 1

Add the following code to the DocumentViewer:

    <DocumentViewer.InputBindings>
        <KeyBinding Key="P" Modifiers="Control" Command="ApplicationCommands.NotACommand" />
    </DocumentViewer.InputBindings>

You can always try using the keydown event as follows:

private void Window_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.P && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
        {
            e.Handled = true; 
        }
    }
