using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Image_task
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void insert_btn_Click(object sender, EventArgs e)
{
try
{
int count;
dall insert = new dall();
int id = Convert.ToInt32(id_txt.Text);
string name = name_txt.Text;
int cat = Convert.ToInt32(cat_txt.Text);
decimal price = Convert.ToDecimal(price_txt.Text);
string image=pic_txt.Text;
count = insert.insrt_up_del("insert into product values('" + id + "','" + name + "','" + cat + "','" + price + "','" + image + "')");
MessageBox.Show("Insert Successfully", "Successfull", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void Form1_Load(object sender, EventArgs e)
{
insert_btn.Enabled=false;
}
private void browse_txt_Click(object sender, EventArgs e)
{
insert_btn.Enabled = true;
openFileDialog1.Filter = "Images (*.BMP;*.JPG;*.GIF,*.PNG,*.TIFF)|*.BMP;*.JPG;*.GIF;*.PNG;*.TIFF|" + "All files (*.*)|*.*";
if (openFileDialog1.ShowDialog()==DialogResult.OK)
{
pictureBox1.Image = new Bitmap(openFileDialog1.FileName);
pic_txt.Text = openFileDialog1.FileName;
}
}
private void search_btn_Click(object sender, EventArgs e)
{
dall select = new dall();
DataTable dt = new DataTable();
dt = select.select("Select * from product");
dataGridView1.DataSource = dt;
//DataGridViewImageColumn img = new DataGridViewImageColumn();
//img.DataPropertyName = "Picture";
//img.Width = 200;
//img.HeaderText = "Picture Column";
//img.ReadOnly = true;
//img.ImageLayout = DataGridViewImageCellLayout.Normal;
//dataGridView1.Columns.Add(img);
//dataGridView1.DataSource = new BindingSource(dt,null);
}
}
}

use data adapter
DataAdapter da = new DataAdapter("Select * from product",youconnection);
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView1.DataSource = dt;
