Problem with Crystal Report

I got a problem with crystal report!

My DBGrid does not display correctly in my report.
There is only the first line of my columns of DBGrid that appears.

Here is a part of my code :

CrystalReport1.Formulas(0) = "NoItem = " & "'" & DBGrid1.Columns(0).Value & "'"
CrystalReport1.Formulas(1) = "Quantity = " & "'" & DBGrid1.Columns(1).Value & "'"
CrystalReport1.Formulas(2) = "Price = " & "'" & DBGrid1.Columns(2).Value & "'"
........
........


Thanks in advance for help!!!
