Is there a way to refresh the aggregate values for a group when a data item in that group has been updated? I have templates for my footer cells that are bound to the aggregate results. But when a data item in that group is updated the aggregates are not recalculated. If I try to call grid.grdProjSummary.InnerDataGrid() the source IEnumerable passed into my custom aggregate function is all items in the grid..

I too have found group footer rows to not update their values when INotifyPropertyChanged has been called.
As a work around I have either had to call rebind on the grid after cells have ended edit or I have my users click on a button to refresh the calculations (calling rebind)
For me this happens when a cell being edited causes a different cell or multiple cells values to change.
Especially when the cell's value that changed is on a different row.
I have also found Group footer sum rows to recalculate correctly and the Cell value to not be updated
