Crystal report objects by their position ?

Question

Hai,
    How can I take the objects from my crystal report according to their position? In my crystal report I have the text objects and field objects the text object text are Roll No, Name, Grade ...etc
    I want to get these values from my crystal report to a string variable with the correct position, means if I change the text objects position such that Name first then Roll No, Grade. Then I have to get the correct sequence(Name, RollNo, Grade)

If any body know how to do this please help me,

Thanking you..
