WPF OnKeyDown Alt+Key combination generates a beep sound
In WPF Controls, a beep sound is generated on Alt+Key keyboard combination.
I have some code which handle specific Alt+Key shortcuts in an override implementation of:
void UIElement.OnKeyDown(KeyEventArgs e);
- Setting e.Handled = true doesn't mute the sound.
- Neither does not calling base.OnKeyDown(e);
- OnPreviewKeyDown behaves in the same way.
How to suppress this sound ?
WinForms apparently had e.SuppressKeyPress = true but that doesn't exist anymore in WPF.

to handle this you should use different event
private void TextBox_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
e.Handled = true;
}
