detecting UP or DOWN of a NumericUpDown

[JulianUK]

afternoon / morning

I'm trying to detect which button (up or down) was fired during the ValueChanged event.

I can tantalisingly see the "pushed" property during debug in my local variables navigator, but can't seem to get at it.

What do I need to do?

Thanks

Julian

On the keypress or the keydown event, you should check it for "Keys.Up" and "Keys.Down". If the up or down keys are handled before the keypress is fired, you may need to overload the control to catch it.

Good Luck,
Kevin

Thanks kmfna, but the keydown (or key..anything) events do not seem to fire upon up/down button press.

Those events fire upon actual keypress on the control. "Keys" doesn't seem to exist anyway.

I am using C# in Delphi 2005 if that makes a difference, but I don't think so.

decimal prevValue=0;
private void numericUpDown1_ValueChanged(object sender, System.EventArgs e)
{
if (numericUpDown1.Value < prevValue)
{
MessageBox.Show("Down");
}
else if(numericUpDown1.Value > prevValue)
{
MessageBox.Show("Up");
}

prevValue = numericUpDown1.Value;

}

Thanks mbde

Unfortunately that's exactly the filthy fix I wrote in already.

Eurgh.

Saves overloading though I suppose.
