>What are the data types involved here. If your BookID is character you can simply create and index on BookID + DTOS(BorrowDate) and use that index as th child order for the grid. If Book_id is numeric you can createw and inde xon STR(book_id,11) + DTOS(BorrowDate) and then set that index as childorder and make the RelationalExpr STR(Book)ID,11).

Ok, I will test it.

But I want to show as follow case:

Asc order for Book_ID,
Desc order for BorrowDate.

So, Str(Book_ID,11) + DTOS(BorrowDate) can give above order request!
In Natural order, generally, BorrowDate will input ascendingly..
but I want to Reverse it to show out Last Borrow Information at the top of Grid row!!
