I group by 3 columns: Country, State, and City
The data are:
Row 1: US, California, LA
Row 2: US, NewYork, NY
Row 3: Japan, -, TK
Then, it will be grouped as the following:
1st Group: US (With Subgroup of California and New York, and with 2nd SubGroup of LA and NY)
2nd Group: Japan (With empty Subgroup, and with 2nd SubGroup of TK)
Like WinTree's FreeForm, is there a way to remove the empty SubGroup Row in the 2nd Group?
(Like having Japan -> TK then instead of Japan -> (1) -> TK)
Is there a way to do this???
No, there is no way to do this in the grid.
Can't we do this with Multiple Bands?
Indeed, can we apply different grouping per band? (Like each band to represent different grouping, and apply individial group-by to each band?)
Hi,
Regard to the above question, is there any way to achieve this (remove the empty group) by any mean? (Multi-Band, or Tree's Free form)
I need something that performs as well as the current wingrid's group-by-row, as I am currently handling more than 1000 rows, and also has like 10-100 groups, each with different level of sub-groups.
Take a look at this thread:

The differences in comparing your requirements to mine:
Thanks for the response.
However, I do have a strong requirement that I have to use BindingList, and not UltraDataSource, and I do handle at least 100 rows with 80 columns, and all the values are updated every second.
Looking at the example, is it possible to achieve it with IGroupByEvaluator?
Or, I was looking into 9.1 library, and it had a new feature "Grouping Columns in Row Layout ". Can this meet my needs?
If Mike has his ears open he might be able to shed some light on that for you. Unfortunately I have not worked with either (still learning the control).
