Why does TDADataTableRules post (TDADataTable) scroll over records

Why does a TDADataTableRules Post trigger the scroll events for the entire dataset?

We have a child DA table of type TDADataTable with a lot of records.
We notice the post triggers the beforescroll and afterscroll events for each record (even if only the single record that the cursor points to has changed)
There is a calculated field in the data item, is this related?

How can we prevent this behaviour?



have you tried to use table.DisableControls / table.EnableControls ?
