Overriding the default keys used to navigate in RadioButtons [WPF] [VB]

[Jayme65]

Hi, In my application, the user has to navigate through RadioButton's group using the keyboard By default, the arrow keys are used to navigate and the space bar used to select the radio button. I would like the 'select' key to be another keyboard key! How should I please process to switch the key used for the button selection by the "A" key, for instance? Thank you for any kind help!

You mean add a underscore (_) to the content? If you do "Radio Button #_1", the 1 will be underlined and a user can hit Alt+1 to select the radio button.

A quick and dirty way would be to use your own RadioButton-derived class that responds to the key press you want, something like:

public class MyRadioButton : RadioButton
{
    protected override void OnKeyDown(KeyEventArgs e)
    {
        if (e.Key == Key.A)
            OnClick();
        else
            base.OnKeyDown(e);
    }
}

Thanks for your reply! No, that's not what I mean (sorry english isn't my mothertongue) I mean, being able to select the radio button which has the focus, with the key "A" instead of the default "SPACE" key!
