Hello,

I use a VT as a sorted list for records.
At first I fill the VT with records by Append method.
I have set IndexFieldNames:='a_key';
If the IndexFieldNames has a value (like 'a_key') adding records takes a lot of time (120 sec).
If the IndexFieldNames has no a value ('') adding records takes a few seconds.

Can I adding records when the IndexFieldNames is empty and then set IndexFieldNames on required fields ?
Will the VT re-sorted after this?

Regards
Michal

If the TVirtualTable.IndexFieldNames value is set for sorting, each time when a new record is added or appended, a dataset will be resorted. To avoid wasteful resorting, set IndexFieldNames value blank, add new records, and then return the previous value for IndexFieldNames. The dataset will perform one sorting.

Hello,

Thank you.
