as far is I know sorting in a ClientDataSet works over the indexDefs.
I can add an indexDef, set the field(s) I want to sort, and over the ixDescending property I can define the direction to sort.

I have a ClientDataSet connected to a dataSource which is the source for a DBGrid.
When I now insert a new record in the ClientDataSet, it’s either inserted at the top of the table (ixDescending = false) or at the bottom of the table (ixDescending = true).

But I want a descending order AND new records should be at the top at the table – not at the bottom.
I tried to change the the indexDefs at runtime to achieve this – but without success.
Somebody has an idea how to do this?

    When you have inserted a record unless you set values for the indexed fields they are NULL, and sorted accordingly.
