This is an odd one. I''m using a v3 grouping grid with a number of CustomSummary objects derived from SummaryBase
At runtime, I sometimes need to change from SummaryType.DoubleAggregate to SummaryType.Custom and vice versa - after I''ve updated some bound table data.
I actually clear the summary objects and then recreate them using GridSummaryRowDescriptor.SummaryColumns.Add()
but have found the first time that I do this the Summary value is NOT being displayed at all. But if I alter them a subsequent time, using the same Factory code, all displays OK.
I can see the correct CreateSummaryMethod and Combine methods being called but if I put a breakpoint on ToString it doesn;t get called
I''ve tried doing things like syncGrid.TableDescriptor.EnsureSummaryDescriptors but this make no difference.
FYI, I''m also setting
syncGrid.Table.TableDirty = true; syncGrid.Table.SummariesDirty = true;

You do also call grid.Refresh() after you made the changes, correct?
Otherwise I can''t explain it. If you post a sample I can look into it.

Yes, I do call refresh. I''ll try to find some time to create a sample app
