    private void Form1_Load(object sender, EventArgs e)
    {
        this.BindDataGridView();
    }

    private void BindDataGridView()
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)),
                            new DataColumn("Name", typeof(string)),
                            new DataColumn("Country",typeof(string)) });
        dt.Rows.Add(1, "John Hammond", "United States");

    {
        btnPrint.Visible = false;
        this.Controls.Add(pnlDetails);
        Graphics grp = pnlDetails.CreateGraphics();
        Size formSize = this.ClientSize;
        bitmap = new Bitmap(formSize.Width, formSize.Height, grp);
        grp = Graphics.FromImage(bitmap);

        Point panelLocation = PointToScreen(pnlDetails.Location);
        grp.CopyFromScreen(panelLocation.X, panelLocation.Y, 0, 0, formSize);
        printPreviewDialog1.Document = printDocument1;
        printPreviewDialog1.PrintPreviewControl.Zoom = 1;
        printPreviewDialog1.ShowDialog();
        btnPrint.Visible = false;
    }

    private void PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
