Datagrid Headers???

[Douglas Gage]

I want to know my headers of datagrid will not be known in advance, the
headers will be parsed at the run time by an array list. How would I be able
to solve the problem:

Before:
datagrid

After: collecting Arraylist which stores header datagrid then it should
print out (I'm binding it from database, this is just a form for user to
fill out, I don't know if the way i'm going is correct)

Header 1 Header2 Header3 Header 4

Thanks
