Getting shift/ctrl/alt states from a mouse event?

Question

In my WPF App, how do I get the state of the shift, ctrl and alt keys in my mouse event handler? I seem to remember in MF

Answer 1

Assuming that you're still in the mouse event handler, you can check the value of Keyboard.Modifiers. I don't think that there is anyway to get modifier information from the event itself, so you have to interrogate the keyboard directly.

Answer 2

As per Andy's answer, you use Keyboard.Modifiers. I figured I would post a little example

Something like this in your event handler should work:

private void MyExampleButton_Click(object sender, RoutedEventArgs e)
{
    if ((Keyboard.Modifiers & ModifierKeys.Control) > 0) {
        System.Diagnostics.Debug.WriteLine("Control is pressed");
    } else {
        System.Diagnostics.Debug.WriteLine("Control is NOT pressed");
    }
}
