GridGroupingControl does not show new record added to datatable

[Jianbo Peng]

I am using a GridGroupingControl binding to a dataset. In the dataset, there are three tables A, B, and C. There are three relations as well: AB, BC, and AC. The grid is set to display table A. Initially, all tables are empty. When I add records a, b and c to tables A, B, and C respectively, record a and b show up correctly in the grid (when I expand record a). But record c in table C does not show up when I expand record a or b. If I close the grid and open it again, binding to the same dataset, all three records are displayed correctly. Two screenshots are attached to show my problem. Do I need to call some function after the records are added into the dataset? Thanks in advance, screenshots_594.zip

I tried to see this problem using the 3.3 RC version in this sample.

Can you tell me how to see the problem in this sample? What version are you using?

In general, you can try setting grid.Table.TableDirty = true followed by grid.Refresh to redraw things entirely.

I was not able to reproduce the problem in the example though (the library used is of version 3.0.1.0). I''ll try a bit more and see if I did anything wrong in the original program. Thanks, Clay.

Clay, I reproduced the error in your example, please see the attached project. When you click the button ''Add to C'', you''ll see it. The thing I changed is that the relation BC has two key columns now. Thanks, GGC_ABC_1956.zip

Clay,

I found the reason. If you update all three tables A, B and C in one function, you have the problem. The work around is to call refresh() function after updating each table.

Thanks for the example. It helped.
