C# working with dynamic controls through classes

[devicemangler]

Hi,

I just started using c# about a week ago and have run into a roadblock when trying to create a function class to reduce the size of my app.

here is my code:

private void NumericUpDown1_ValueChanged(object sender, System.EventArgs e) {
 if (pts > 0) {
  NumericUpDown1.Maximum = 5
  NumericUpDown2.Maximum = 5
  NumericUpDown3.Maximum = 5
  NumericUpDown4.Maximum = 5
  NumericUpDown5.Maximum = 5
  if (NumericUpDown1.Value > NumericUpDown1LastValue) {
   pts = pts - 1;
  }
  if (NumericUpDown1.Value < NumericUpDown1LastValue) {
   pts = pts + 1;
  }
  NumericUpDown1LastValue = NumericUpDown1.Value;
  lblPts.Text = pts.ToString();
  if (pts == 0) {
   NumericUpDown1.Maximum = NumericUpDown1.Value;
   NumericUpDown2.Maximum = NumericUpDown2.Value;
   NumericUpDown3.Maximum = NumericUpDown3.Value;
   NumericUpDown4.Maximum = NumericUpDown4.Value;
   NumericUpDown5.Maximum = NumericUpDown5.Value;
  }
  if (pts == 0) {
   if (NumericUpDown1.Value < NumericUpDown1LastValue) {
    pts = pts + 1;
   }
   NumericUpDown1LastValue = NumericUpDown1.Value;
   lblPts.Text = pts.ToString();
  }
 }
 

I have over 60 NumericUpDown controls that are handled by this handler, but each have very slight differences, so i've been using individual handlers like the one above to handle each one, and i've just been editing out the differences. if there is a way to make a generic function class that would be able to do this that basically just generalizes NumericUpDown1 and lblPts so i can drop them in as parameters it would be swell.
