GridGroupingControl, Grouping refresh issue with DataRelations

[Shawn Hanatani]

I''ve attached a sample... I''m using version 4.1.0.50 and the GridGroupingControl. I''m having issues with the groupings correctly refreshing when the underlying DataTable is updated from sperate thread (haven''t tried updating on UI thread but not really an option) and the column being grouped on is populated via a DataRelation join with another table. Please check out the sample, simple grid with a ColorId and Colors fields. The Colors field is populated via a seperate Colors table. When you click on the start button new rows are added but it doesn''t group properly.

Hi Shawn,
In your worker thread, try calling Table.TableDirty after adding the new rows.
This will recategorize all the records in the table.

this.gridGroupingControl1.Table.TableDirty = true;

Best regards,
