copied!<p>The simple way to do this would be data binding. In WPF this is quite easy. You can bind the data from one control to another. Below I have bound a TextBox, which has taken the user input, to a Label which displays it.</p> <pre><code><Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="45,55,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" /> <Label Content="{Binding ElementName=textBox1, Path=Text}" Height="28" HorizontalAlignment="Left" Margin="45,135,0,0" Name="label1" VerticalAlignment="Top" Width="142" /> </Grid> </code></pre> <p></p> <p>The more complex answer would be to do Command binding. What this does is catches specific key bindings on a UserControl or Window and executes a given command. This is a little more complex because it requires you to create a class that implements ICommand.</p> <p>More info here: <a href="http://msdn.microsoft.com/en-us/library/system.windows.input.icommand.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.windows.input.icommand.aspx</a></p> <p>I personally am a big fan of the RelayCommand implementation by Josh Smith. There is a great article <a href="http://msdn.microsoft.com/en-us/magazine/dd419663.aspx#id0090051" rel="nofollow">here</a>.</p> <p>In short though you can do this.</p> <p><strong>XAML:</strong></p> <pre><code><Window.InputBindings> <KeyBinding Key="Escape" Command="{Binding KeyPressCommand}"/> </Window.InputBindings> </code></pre> <p><strong>CODE:</strong> You will need to create a RelayCommand Class.</p> <pre><code>public class RelayCommand : ICommand { private readonly Action<object> _execute; private readonly Predicate<object> _canExecute; public RelayCommand(Action<object> execute, Predicate<object> canExecute) { if (execute == null) throw new ArgumentNullException("execute"); _execute = execute; _canExecute = canExecute; } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } public void Execute(object parameter) { _execute(parameter); } public bool CanExecute(object parameter) { return _canExecute == null || _canExecute(parameter); } </code></pre> <p>And then to implement this in your main window you will need to do this.</p> <pre><code> private RelayCommand _keyPressCommand; public RelayCommand KeyPressCommand { get { if (_keyPressCommand== null) { _keyPressCommand = new RelayCommand( KeyPressExecute, CanKeyPress); } return _keyPressCommand; } } private void KeyPressExecute(object p) { // HANDLE YOUR KEYPRESS HERE } private bool CanSaveZone(object parameter) { return true; } </code></pre> <p>If you go with the second option I really suggest you take a look at the MSDN article by Josh Smith.</p>
