WPF CommandBinding not working - wpf

Question

I have a button in WPF window. I want to display a message by both pressing left mouseclick and by clicking Ctrl+F. I want most of the code in XAML. Code is as given below.
My problem is that mouse click is working for me but not the key press. Can anybody please help me. Thanks in advance.
MyWindow.xaml
<Window x:Class="Commands_Xaml.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>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="164,88,0,0" Name="button1" VerticalAlignment="Top" Width="75">
<Button.CommandBindings>
<CommandBinding Command="ApplicationCommands.Find" Executed="CommandBinding_Executed"/>
</Button.CommandBindings>
<Button.InputBindings>
<KeyBinding Key="F" Modifiers="Control" Command="ApplicationCommands.Find"/>
<MouseBinding MouseAction="LeftClick" Command="ApplicationCommands.Find"/>
</Button.InputBindings>
</Button>
</Grid>
</Window>
MainWindow.xaml.cs
namespace Commands_Xaml
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
//ApplicationCommands.Find.InputGestures.Add(new KeyGesture(Key.F,ModifierKeys.Control));
//ApplicationCommands.Find.InputGestures.Add(new MouseGesture(MouseAction.LeftClick));
//CommandBinding bindingObject = new CommandBinding();
//bindingObject.Command = ApplicationCommands.Find;
//bindingObject.Executed += new ExecutedRoutedEventHandler(CommandBinding_Executed);
//this.CommandBindings.Add(bindingObject);
}
private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
MessageBox.Show("Button clicked");
}
}
}

Move the command binding / input binding to the window level and use the Command property of the button instead of trying to use a MouseBinding.
<Window x:Class="WpfApplication2.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">
<Window.CommandBindings>
<CommandBinding Command="ApplicationCommands.Find" Executed="CommandBinding_Executed" />
</Window.CommandBindings>
<Window.InputBindings>
<KeyBinding Command="ApplicationCommands.Find" Key="F" Modifiers="Control" />
</Window.InputBindings>
<Grid>
<Button Command="ApplicationCommands.Find" Content="Button" HorizontalAlignment="Left" Margin="206,152,0,0" VerticalAlignment="Top" Width="75"/>
</Grid>
</Window>
UPDATE
To have different behavior based on different button clicks, this can be accomplished a few ways. Here are two:
Use a different command for each button:
<Button Command="ApplicationCommands.Find" Content="Button1" />
<Button Command="ApplicationCommands.Print" Content="Button2" />
Use CommandParameter:
<Button Command="ApplicationCommands.Find" CommandParameter="Find1" Content="Button1" />
<Button Command="ApplicationCommands.Find" CommandParameter="Find2" Content="Button2" />
And for the KeyBinding:
<KeyBinding Command="ApplicationCommands.Find" CommandParameter="Find3" />
You can access this property in the CommandBinding.Executed handler:
private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
if (e.Parameter as string == "Find1")
{
//Find1
}
else if (e.Parameter as string == "Find2")
{
//Find2
}
else if (e.Parameter as string == "Find3")
{
//Find3
}
}
