Master WindowS Form for Windows App

[Winla]

Find a lot talking about MasterPage for ASP.NET, but Couldn't find a sample master winform for business app.

I am looking for something like this:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace MyNS
{
    public partial class frmCommon : Form
    {
        private  Form _CallingForm;
        private string _CallingRole;
        private string _UserRole;


        public Form CallingForm
        {
            get { return _CallingForm;}
            set { _CallingForm =value;}

        }
        public string CallingRole
        { 
            get {return _CallingRole;}
            set {_CallingRole =value ;}
            
        }
        public string UserRole
        {
            get { return _UserRole; }
            set { _UserRole = value; }
        }

        public frmCommon()
        {
            InitializeComponent();
        }

        public frmCommon(Form callingform,  string callingrole, string userrole)
        {
            _CallingRole = callingrole;
            _CallingForm = callingform;
            _UserRole = userrole;

            InitializeComponent();
        }

        public virtual void FormFormat{}
        public virtual Bool FormValid { }
        public virtual Bool FormClean { }
        public virtual Bool FormSave { }
        public virtual bool FormLoad { }
 
    }
}
