Screen Resolution Program in C#.net

Simply says, Display Resolution or Monitor Resolution. I give the demo for Screen Resolution. It's a very simple and easily understandable How to maximize a form without using Maximize Button? 
Use this Code.
In the Namespace

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
//Form Loading
        private void Form1_Load(object sender, EventArgs e)
        {
            // To get Current Screen Resoltion
            int tempwidth = Screen.PrimaryScreen.Bounds.Width;
            int tempHeight = Screen.PrimaryScreen.Bounds.Height;
            int tempX = Screen.PrimaryScreen.Bounds.X;
            int tempY = Screen.PrimaryScreen.Bounds.Y;
            this.Width = tempwidth;
            this.Height = tempHeight-15;
            this.Location = new Point(tempX, tempY);
            dataGridView1.Width = tempwidth;
            dataGridView1.Height = tempHeight;
            int tempcol = tempwidth / 5;
            dataGridView1.Columns[0].Width = tempcol;
            dataGridView1.Columns[1].Width = tempcol;
            dataGridView1.Columns[2].Width = tempcol;
            dataGridView1.Columns[3].Width = tempcol;
            dataGridView1.Columns[4].Width = tempcol;
            dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
        }
