   Copy Code

   C1PrintPreviewControl ppc = new C1PrintPreviewControl(); Controls.Add(ppc); ppc.Dock = DockStyle.Fill; C1PrintDocument pdoc = new C1PrintDocument(); C1PrintDocument pdoc2 = new C1PrintDocument(); C1MultiDocument mdoc = new C1MultiDocument(); pdoc.Body.Children.Add(new C1.C1Preview.RenderText("Hello!")); pdoc2.Body.Children.Add(new C1.C1Preview.RenderText("World!")); mdoc.Items.Add(pdoc); mdoc.Items.Add(pdoc2); ppc.Document = mdoc; mdoc.Generate();

This code loads two C1PrintDocument into the C1MultiDocument component and displays the documents in a C1PrintPreviewControl at run time.
