Moment. Note that allRecordsSortedByField do NOT contains this new RecID.

Because when you have create it this record did not exists.
You need self append new item into array and item will go into END of array.
 
So this will be like Windows do :-)

Well I see next way:

- after add of new record you need create new set and sort it again.

- then you can use NEW function which we can add:
            
    index = Varray.IndexOf( recid )

So you can set correctly yor slider.
