wpf button click as keyboard output

I have two button name "A", and "B" want to click them equal to click keyboard A and B buttons. So any one can give me a quick way to achieve it.

Thanks

Solution

  • I'd do it the following way. First add event handler for the key down event of window or some other parent container:

    <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" KeyDown="Window_KeyDown" Width="525"> [...]

    And the event handler:

    private void Window_KeyDown(object sender, KeyEventArgs e)
{
        if (e.Key == Key.A)
            ButtonA.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
        else if (e.Key == Key.B)
            ButtonB.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
}
