用于打印窗口的打印预览不适用于C＃

Question

我正在尝试屏幕捕获窗体，提供打印预览然后打印。表单在纸张上打印，但是prin预览显示消息“文档不包含任何页面”/

以下是我的代码中的相关摘要。请让我知道我哪里出错了。

 Bitmap bmp; // Variable for Bitmap of actual page to print

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e) //Click to Print
    {
        Graphics g = this.CreateGraphics();
        bmp = new Bitmap(this.Size.Width, this.Size.Height, g);
        Graphics mg = Graphics.FromImage(bmp);
        mg.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
        //printPreviewDialog1.ShowDialog();
        //printDocument1.Print();

        printPreviewDialog1.Document = printDocument1;
      //  printPreviewDialog1.PrintPreviewControl.Zoom = 1;
        printPreviewDialog1.ShowDialog();
}

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
     {
          e.Graphics.DrawImage(bmp, 0, 0);



    }
