How to Inherit button with code from form1 to form2

I have a main form which is called form and a second form called form2. Form contains a button with a coded function inside. Now on my form2 I have the same button which performs the same function on form or which I want it to perform the same function as form1.

On form2 I have created a button of which I want it to use the same function from the form1. Now I want to be able to click the button from form2 and it calls the button funtion from form1.

I have done this but I don't know how I can make it work

Form1 (mainform)

    public Button newButton
    {
        get
        {
            return btnNewfile;
        }
    }
    public void SetLanguage(string cbolang)
    {
        cboLanguage.SelectedValue = cbolang;
    }

Form2

    public frmMain_Page _frmMainform;

    public FrmLanguage(frmMain_Page _frmMainform)
    {
        InitializeComponent();
        this._frmMainform = _frmMainform;
    }

    public frmMain_Page _Main
    {
        get;
        set;
    }

    //from this button I can't get the main button from the main form
    private void btnCreatFile_Click(object sender, EventArgs e)
    {
        _frmMainform.newButton.btnNewfile; 

       //Error  19  'System.Windows.Forms.Button' does not contain a definition for 'btnNewfile' and no extension method 'btnNewfile' accepting a first argument of type 'System.Windows.Forms.Button' could be found (are you missing a using directive or an assembly reference?)
