Detecting multiple PageUp/PageDown key presses

I have a NumericUpDown control in WinForms. The Up/Down arrow keys increase/decrease the value by 1. I want to map the PageUp/PageDown keys for larger increments.

The Control.KeyPress event does not get fired with the PageUp/PageDown keys and if I use the Control.KeyUp/Control.KeyDown events, the combination fires only once even if the user keeps the keys pressed for a while.

How could I trap multiple PageUp/PageDown keys presses during long key presses?

Strange to say, but I cannot reproduce this issue. I have a new winform instance, numericUpDown control with default property` values and KeyDown event handler works perfectly with long key press:

private void numericUpDown1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.PageDown)
            numericUpDown1.Value -= 10;
        else if (e.KeyCode == Keys.PageUp)
            numericUpDown1.Value += 10;
    }

Can you provide your code in the event handlers? /Sorry, I know Im not supposed to ask for clarification in the answer, but I can`t write comments./
