I'm working with UltraWinGrid (Infragistics2.Win.UltraWinGrid.v11.1 11.1.20111.2111) with 2 UltraCombo columns. A dropdownlist in a grid cell whose list values are dependent on another cell.(Combo1, Combo2).
Load all values in Combo2 and data will filter according to Combo1 in BeforeCellActivate event.... (http://blogs.infragistics.com/winforms/codesamples/creating-a-dropdown-list-in-a-grid-cell-whose-list-values-are-dependent-on-another-cell.aspx)
It's ok for introducing new rows because combo values are filtered.
But, to open the form and load grid with data values, the Combo2 description is wrong.

Example:
STATES: (Combo1)
IdState - Name
================
1         - State1
2         - State2

Combo1.ValueMember = IdState
Combo1.DisplayMember = Name

CITIES: PK(IdState,IdCity) (Combo2)
IdState - IdCity - Name
========================
1         - 1          - City1
2         - 1          - City2

Combo2.ValueMember = IdCity
Combo2.DisplayMember = Name

CUSTOMER (table):
IdCustomer - Name          - IdState(Combo1) - IdCity(Combo2) -.....
===================================================
1                - Customer1  - 2                          - 1

CUSTOMER (columns of the grid):
IdCustomer - Name         - State (Combo1)  - City (Combo2)
========================================================
1                - Customer1   - State2                - City1 --> (ERROR! Is City2!!)


When loading the grid and display customer data, such as Combo2 is full load, shows the description 'City1' (ERROR! Is City2!!)(the combo2 it's not filtering).

How can I solve the problem????
Must be filtered the combo in every row to the grid to display correct data values????
How can I work with dependent combos??

Thanks in advance.
