VS 2010 Printing a form with complete datagridview records

Hi there,

I am trying to print my form with all records inside datagridview, coding i used is

PrintForm1.PrintAction = Printing.PrintAction.PrintToPreview
PrintForm1.Print(Me, PowerPacks.Printing.PrintForm.PrintOption.Scrollable)

this coding prints form but prints only datagridview's 15 records as on screen, there are 250 records in datagridview.

Please help

Thanks
