Searching up which UI object triggers a specific method

Hi, I'm editing an existing Windows Forms desktop application written in C# and have a few methods that I don't know which UI element calls. For example, I have a

private void button1_Click(Object sender, EventArgs e) {}

but there is no UI element named button1. Is there a way to search all UI elements and see if any of them are calling this method for any of their events?

Thanks.
