        private void MyPrintDocument_PrintPage(object sender,
    System.Drawing.Printing.PrintPageEventArgs e)
        {
            bool more = MyDataGridViewPrinter.DrawDataGridView(e.Graphics);
            if (more == true)
                e.HasMorePages = true;
        }

        private void toolStripButton1_Click(object sender, EventArgs e)
        {
            if (SetupThePrinting())
            {
                PrintPreviewDialog MyPrintPreviewDialog = new PrintPreviewDialog();
                MyPrintPreviewDialog.Document = MyPrintDocument;
                MyPrintPreviewDialog.ShowDialog();
