Hi, can UltraGrid meet the requirement as follows:

there are 6 rows and 3 columns, the target rows will be 4 rows after it is group by with the COL1 and COL2.
(just like the SQL group by: SELECT * FROM XXX GROUP COL1,COL2)

The raw data given by XML:
==========================
|#|COL1 | COL2 | COL3
|=|======================
|1|A    | B    | 2
|-|----------------------
|2|A    | B    | 1
|-|----------------------
|3|M    | R    | 4
|-|----------------------
|4|X    | C    | 5
|-|----------------------
|5|X    | C    | 2
|-|----------------------
|6|X    | N    | 6
|-|----------------------

The target rows to by shown in grid on the winform:
+++++++++++++++++++++++++++++++++++++
==========================
| |COL1 | COL2 | COL3
|=|======================
|-|A    | B    | 3
|-|----------------------
|-|M    | R    | 4
|-|----------------------
|-|X    | C    | 7
|-|----------------------
|-|X    | N    | 6
|-|----------------------

is it possible for UltraGrid?

Thansk a lot.
