I have a parent-child form. The child data is displayed in non-grid controls on a pageframe which is itself inside a pageframe. Since the child table is not within a grid, I need a way to navigate the records in the child table. I thought to do this via a dropdown combo with the following code:

** cbo.InteractiveChange
this.Value = this.value
select rta_payments    && the child table
locate for pmt_id = val(this.Value) and tip_id = tip.tip_id
select tip   && the parent table
this.Parent.refresh   && refresh the page displaying the child data
dodefault()

This seems to work except when subsequently clicking on the page or any of its controls, I find the child record pointer jumps back to the first child record and does not stay on the one that was selected in the combo. Watching this in the debugger I find that this click triggers a page.activate which contains a page.refresh, but there is nothing there or in any of its controls that would cause a move in the record pointer.

Any thoughts on what might be going on? Or is my approach flawed?
