GWT DataGrid: how to scroll to the top

[Cedric]

When changing the content of my DataGrid I would like the grid to
scroll back to the top but it does not happen automatically.

I have two grids side by side (see http://code.google.com/p/bug4j/ )
and when the selection changes on the left, the content changes on the
right.

I found a workaround but it isn't pretty:
final DataGrid<BugHit> ret = new DataGrid<BugHit>(PAGE_SIZE){
@Override
public void setRowData(int start, List<? extends BugHit>
values) {
final HeaderPanel headerPanel = (HeaderPanel)
getWidget();
final ScrollPanel scrollPanel = (ScrollPanel)
headerPanel.getContentWidget();
scrollPanel.scrollToTop();
super.setRowData(start, values);
}
};

1) Did I miss something?
2) Should I file a bug?
3) What is the bug? a) the DataGrid should expose the ScrollPanel or
b) DataGrid it should scroll automatically to the top?

I'd go with 3a. Your usecase may not be everyone else's usecase (although it makes sense).

Added my use case (lazy row rendering) to the bug page. It requires
scrollPanel access too.
