hi I have been trying to draw a grid to a picture box. I have the grid drawn on the windows form itself but when I try to draw to the picture box it doesn`t work.
instead the grid draws around the area of the picturebox rather than within the picture box itself.
below I have posted my code any help would be greatly apreciated.
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;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
// int r = 20;
// int c = 20;
// const bool[,] grid1 = new bool[r, c];
// const bool[,] grid2 = new bool[r, c];
const bool ALIVE = true;
const bool DEAD = false;
// int readptr = grid1;
// int writeptr = grid2;
int n = 0;
private void swappointer()
{
// bool[,] temp;
// temp = readpoint;
// readpoint = writepoint;
// writepoint = temp;
}
private void draw()
{
//if (writeptr[r, c] == ALIVE)
{
// pen = black;
}
// else
{
// pen = white;
}
// g.DrawRect(pen, xoffset, yoffset);
}
protected override void OnPaint(PaintEventArgs e)
{
}
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
Pen linePen = new Pen(System.Drawing.Color.CornflowerBlue);
Graphics grphx = this.CreateGraphics();
grphx.Clear(this.BackColor);
for (int i = 1; i < 21; i++)
{
//Draw verticle line
grphx.DrawLine(linePen,
(this.ClientSize.Width / 20) * i,
0,
(this.ClientSize.Width / 20) * i,
this.ClientSize.Height);
//Draw horizontal line
grphx.DrawLine(linePen,
0,
(this.ClientSize.Height / 20) * i,
this.ClientSize.Width,
(this.ClientSize.Height / 20) * i);
}
linePen.Dispose();
//Continues the paint of other elements and controls
base.OnPaint(e);
}
private void button1_Click(object sender, EventArgs e)

private void button2_Click(object sender, EventArgs e)
