Hi, I'm using fastreport ver 4
I want to create a report with three level, and with 1 query.
So I used GroupHeaders for create my report.
But I should show ColumnHeader for each group and I have problem with this.
Please Help me How can I show ColumnHeader for each GroupHeader and each Group has different FieldsName.
Thanks.

not clear as to what you are trying to describe.
look at the main demo Basic reports nested groups report,
is this what you are trying to describe.

I wanna create a Report like three level grid with GroupHeaders(DrillDown Property = True). In Nested Groups sample each record has own columnheader caption before FieldValue for example (CustNo: 10), but I don't want to do this. I want to know that how can I add ColumnHeader for each group on top of it Like a Grid (Like Master/Detail Reports but Beacuse Of I Wanna use DrillDown Property In My Report I should use GroupHeaders).
I think that if I use Child band and attach it to each groupheader, this solve my problem. But after I do that the resualt not acceptable. Becuase when I collapse the groupheader, this child band don't collapse so this is not good for me.
Please help me. Thanks
