i use this code to increase the height header of crystal report
CrystalReportViewer1.ReportSource = print_report1 '
msgbox(print_report1.Section2.Height) '// print value 4000
print_report1.Section2.Height = 10000
msgbox(print_report1.Section2.Height) '// print value 10000
CrystalReportViewer1.Refresh()
the height change from 4000 to 10000 when print the new height value , but not appear the new height in the viewer ?
EDIT '
The change appears only when the update icon is clicked in the viewer and does not appear by the code
CrystalReportViewer1.Refresh()
i fixed it after long search , i just use this code to update shape of report
CrystalReportViewer1.RefreshReport()
