Do you know what composition over inheritance is?

In the form where you have MasterReset you should do something like this:

Llet's suppose that in your second form you have something like this, and let's suppose your "mainform" will be called "MasterForm".

public partial class Form1 : Form
{
    private MasterForm _masterForm;  

    public Form1(MasterForm masterForm )
    {
        InitializeComponent();
        _masterForm = masterForm;  

    }
}

Here's the code in your masterForm Class:

 private void button2_Click(object sender, EventArgs e)
 {
     Form1  form1 = new Form1(this);

 } 

Here's in your form1:

private void btn_MasterReset_Click(object sender, EventArgs e)
{
    _masterForm.MasterReset();
} 

Hope this helps!
