Question

I would like to just have user input registered when changing the radio buttons on my form but obviously it triggers from program changes too which I thought I could fix by just using a boolean, this worked in a way but here is the problem:

At the moment I have two radio buttons linked and when one is triggered it triggers the other one. What is the easiest way to filter input when both methods are being called when I change a single radio button?

You can try adding the handlers after you set the value of the control:

public Form1() {
  InitializeComponent();

  radioButton1.Checked = true;
  radioButton1.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
  radioButton2.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
}

private void radioButton_CheckedChanged(object sender, EventArgs e) {
  RadioButton rb = (RadioButton)sender;
  if (rb.Checked)
    MessageBox.Show("User checked " + rb.Text);
}
