# 4723 TDataSet Changes for FMX Grid Issue Cause Issues with Scrolling in VCL TDBGrid Control

---

Since insensitive datasets are sequenced, the vertical scrollbar of the dbgrids jump up and down when we navigate a dataset if the order of the result set is not the primary key. It seems that the scrollbar is always showing the relative position of the current row as defined by its Primary Key order.

It's easy to reproduce in EDB Manager. Something Like: SELECT * FROM <TableName> ORDER BY <NonPrimaryKeyColumn> You have to force the result set to be Insensitive and the <NonPrimaryKeyColumn> doesn't define an order that coincides with the primary key index.
