Detect if Modifier Key is Pressed in KeyRoutedEventArgs Event

Question

I have the following code:

public void tbSpeed_KeyDown(object sender, KeyRoutedEventArgs e)
{
    e.Handled = !((e.Key >= 48 && e.Key <= 57) ||         


        

Answer 1

Bitwise AND the Modifiers property of Keyboard with Shift Key -

bool isShiftKeyPressed = (Keyboard.Modifiers & ModifierKeys.Shift)
                         == ModifierKeys.Shift;

Try this too-

bool isShiftKeyPressed = (ModifierKeys & Keys.Shift) == Keys.Shift;

OR

Control.ModifierKeys == Keys.Shift
