I'm not sure if you mean scroll the datagrid, or scrollbars on the hbox.
DataGrid:
scrollToIndex () method
public function scrollToIndex(index:int):Boolean
Ensures that the data provider item at the given index is visible. If the item
is visible, the verticalScrollPosition property is left unchanged even if the
item is not the first visible item. If the item is not currently visible, the
verticalScrollPosition property is changed make the item the first visible
item, unless there aren't enough rows to do so because the
verticalScrollPosition value is limited by the maxVerticalScrollPosition
property.
HBox:
Ifyou mean the scroll bar on a HBox then use the scrollPosition property of the
HBox scrollbar. The HBox has a scrollbar property: verticalScrollBar.
So, for your hbox it would be tile2.verticalScrollBar.scrollPosition = 0;

Subject: [flexcoders] How to reset a scrollbar - would really appreciate some
assistance please
I want to reset a scroll bar to the top when returning to a dynamically
populated datagrid in my app. Basically the datagrid displays info about
different students so clicking on a students name in a list takes you to this
datagrid. Problem is if I am looking at the data of one student and scroll down
this info, then leave this section and return as a different student, the
scroll bar is where I left it with the previous student
Here is the code of the relevant section. As no scroll bar is explicitly
coded, I do not know how to ensure it resets.
<mx:VBox width="720" id="tile2" height="190">
<mx:Repeater id="markSheetRepeater"
dataProvider="{this.markSheetXMLData}" >
<local:MarkSheetItem
xmlItem="{markSheetRepeater.currentItem}" id="markSheetItem">
</local:MarkSheetItem>
</mx:Repeater>
</mx:VBox>
Btw this is Flexbuilder 2
Thanks in advance
Paul
