I have an UltraGrid bound to a BindingSource, where the DataSource is a BindingList<T> and new records are added to the list.  Each record has a time stamp property/column and the typical usage is to sort by the time stamp column in descending order, i.e. the latest record appears at the top.

If the user scrolls down to look at a particular record, it can be annoying when new records come in because the visible position of the row changes (moves lower in the grid).  I have the following code to try to work around this, but it seems the call to set the "FirstRow" on the RowScrollRegion is completely ignored.

private void _grid_AfterRowRegionScroll(object sender, RowScrollRegionEventArgs e) {

_firstVisibleRow = e.RowScrollRegion.FirstRow;

}

private void _bindingSource_ListChanged(object sender, ListChangedEventArgs e) {

_grid.DisplayLayout.Bands[0].SortedColumns.RefreshSort(false);

if (_grid.DisplayLayout.RowScrollRegions[0].ScrollPosition != 0 && _firstVisibleRow != null)

  _grid.DisplayLayout.RowScrollRegions[0].FirstRow = _firstVisibleRow;

}

I've also confirmed that _firstVisibleRow is being set to the correct row and is still the correct row when setting "FirstRow" property.

Am I making an incorrect assumption that FirstRow should adjust the scroll region to make this row the first visible row?
