Solution 1

If the button is in the user control, have it raise an event passing the data in the args that the form can hook in to.
Pass value between forms using events[^]

1. Declare a custom EventArgs that can hold the information you wish to pass on from the UserControl to the Form.
2. Declare an Event in the UserControl that takes in the EventArgs declared above.
3. Make the Form subscribe to the event in the Form's Load event.
4. When raising the event from the UserControl, build a new instance of the custom EventArgs with the information you wish to pass and pass it along when you raise the event.
5. The form's method that handles the UserControl's event will get the custom EventArgs instance. Use it in your form.
