I have a grid with the outlook group by turned on.  My grid has about a dozen rows and I select a column to group by that leaves anywhere from 2 to 5 rows in a group.  I expand a group that contains 3 rows and I delete the row that is displayed in the middle.  I wasn't sure what to expect with my groups after I did this.  If I use the RefreshSort on the SortedColumnsCollection then all of my groups are set to collapsed but the grid data is correct.  Using RefreshSortPosition on the individuals rows doesn't seem to refresh the grid correctly (I get a bogus 3rd record).  I have seen a couple other posts regarding the RefreshSortPosition not working correctly if rows are grouped.  Is this a bug?   And I've also seen a few posts about the groups automatically collapsing with the RefreshSort.  I'd post code but we are running Infragistic controls through third-party language with a CLR bridge.

Does anyone have an example of how they handled this situation?  I can keep track of all of my expanded groups and their value before refreshing the grid's data but I can't think of a good grid event to hang my hat on to put this logic so I don't have to write it for every grid in our app.
