If you want to expand a particular group, you may use the ExpandGroup() method of the grid. In case you require only a single group to be expanded at a time, you may benefit from the approach demonstrated in this blog post. However, your implementation may be similar to:
if((e.Row as GridViewGroupRow).IsExpanded == true)
if(lastExpandedGroupRow != null)
lastExpandedGroupRow.IsExpanded = false;
lastExpandedGroupRow = e.Row as GridViewGroupRow;
