    copied!<p>I need some assistance in getting WPF KeyBindings working when being called from a WinForm application. I've created what I think is the basic parts to demonstrate the problem. I can provide an sample application if that helps.</p> <p>The WinForm application starts a form which has a button that calls the WPF </p> <pre><code>Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim view As New WpfPart.MainWindow System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(view) view.ShowDialog() End Sub </code></pre> <p>With WPF view creates it's view model and sets up the keybings:</p> <pre><code>&lt;Window x:Class="WpfPart.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:vm="clr-namespace:WpfPart.ViewModels" Title="MainWindow" Height="350" Width="525"&gt; &lt;Window.DataContext&gt; &lt;vm:MainWindowViewModel /&gt; &lt;/Window.DataContext&gt; &lt;Window.InputBindings&gt; &lt;KeyBinding Key="Escape" Command="{Binding OpenCommand}" Modifiers="Control" /&gt; &lt;/Window.InputBindings&gt; &lt;Grid&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>The ViewModel uses a DelagateCommand to hopefully link everything up</p> <pre><code>using System; using System.Windows; using System.Windows.Input; using WpfPart.Commands; namespace WpfPart.ViewModels { class MainWindowViewModel { private readonly ICommand openCommand; public MainWindowViewModel() { openCommand = new DelegateCommand(Open, CanOpenCommand); } public ICommand OpenCommand { get { return openCommand; } } private bool CanOpenCommand(object state) { return true; } private void Open(object state) { MessageBox.Show("OpenCommand executed."); } } } </code></pre> <p>Can anyone see where it is going wrong, the keypress does nothing?!?</p>
