How do I ignore simple events firing when changing control states in C# Windows Forms?

To fix the issue you can do For the more general case, if you have complex relations between the controls, you could check which control fired the event by checking its own Focused property:
code :
private void chkState_CheckedChanged(object sender, EventArgs e)
{
    if (chkState.Focused)
        RedrawStuff();
}

private void numStateValue_ValueChanged(object sender, EventArgs e)
{
    if (!chkState.Checked)
        chkState.Checked = true;

    if (numStateValue.Focused)
        RedrawStuff();
}

Spinner OnItemSelectedListener

it helps some times In Mono for Android a lot of listener interfaces have been translated to C# events, including this one. In this case you can hook into the ItemSelected event instead of having to create a listener. Xamarin has a full example of using a spinner available here.
Edit:
code :
int initialSpinnerPosition = spinner.SelectedItemPosition;
spinner.ItemSelected += (sender, args) =>
                        {
                            if (args.Position != initialSpinnerPosition)
                            {
                                // do stuff
                            }
                        };

Trying to add an onItemSelectedListener to a spinner

I wish this help you I'm trying to add an onItemSelectedListener to a spinner. I've looked at other questions on here with similar problems and it doesn't seem to work. I'm not getting an error when it runs, but the toast I'm trying to create doesn't pop up. , Here is how spinner can be used
code :
// Reference the spinner    
    Spinner spinner = (Spinner) findViewById(R.id.spinner);

    // Set spinner onItemClickListener
    spinner.setOnItemSelectedListener(new OnItemSelectedListener() { 

            @Override 
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {

                Toast.makeText(secActivity.this, "You have clicked", Toast.LENGTH_SHORT).show();
            } 
        });

this one helps. There is some advice on how to achieve your functions' idempotency.
There are FieldValue.arrayUnion() & FieldValue.arrayRemove() functions which safely remove and add elements to an array, without duplicates or errors if the element being deleted is nonexistent.
