NumericUpDown differentiate up and down

I have a WinForm with some numreicUpDown Controls, i want to know if the value has been incremented or decremented. the control fires the event value changed for both situations, and as far as i can understand the programm calls the methods UpButton and DownButton. Is there any other way to know how the value has been changed or do i have to do this with this methods(like firing eventor implementig my code in Up-Down-Button)

Solution

  • There is no standart way to do this. I sugest to remember the old value and compare it with new one 

    decimal oldValue;

private void ValueChanged(object sender, EventArgs e)
{
    if (numericUpDown.Value > oldValue)
    {
    }
    else
    {
    }
    oldValue = numericUpDown.Value;
}
