Mike - Thank you for the link. Looks fairly straight forward but I  cannot quite figure out the correct vb 2010/10.3 Win form syntax for the following:

 UltraGridBand rootBand = this.citiesDropDown.DisplayLayout.Bands[0];   

        rootBand.ColumnFilters.ClearAllFilters();   

        rootBand.ColumnFilters["StateID"].FilterConditions.Add

if you could point me in the right direction i would appreciate it(if this was a really stupid question, I apologize in advance :)

Thanks

Yeah that makes sense.

thanks Mike

Hi Al,

The combo doesn't have any built-in functionality to remove duplicates from the list. You would have to do that on the data source, or else filter out the duplicates yourself, which probably wouldn't be very efficient.

thanks Mike. that did work. i will mark as accepted answer.

But i have another question regarding the rows in _cbbrok. is there way to display only unique values?

i've bound it do a datasource that is distinct by another field in the datatable. i'm binding this cbo to the same data but displaying a different field. (one that happens to be repeating). can i just show distinct?

lmk if i'm not making sense.

thanks

Al

You could simplify this a little, by using

foreach (var row in _cbbrok.Rows.GetFilteredInNonGroupByRows())

This will loop through only the visible rows, so you do not need the IsFilteredOutCheck. This would also account for rows that you hid explicitly by setting the Hidden property, in addition to those rows that are filtered out.

found a solution..loop. :/

  private void gridData_AfterCellUpdate(object sender, CellEventArgs e)
        {
            if (e.Cell.Column.Key == "PORTFOLIO")
            {
                UltraGridBand brokerBandToFilter = this._cbbrok.DisplayLayout.Bands[0];
              
                brokerBandToFilter.ColumnFilters.ClearAllFilters();
                brokerBandToFilter.ColumnFilters["TRADE_TYPE"].FilterConditions.Add(FilterComparisionOperator.Equals, e.Cell.Row.Cells["TRADE_TYPE"].Value);
                brokerBandToFilter.ColumnFilters["PORTFOLIO"].FilterConditions.Add(FilterComparisionOperator.Equals, e.Cell.Row.Cells["PORTFOLIO"].Value);
                if (_cbbrok.Rows.VisibleRowCount > 0) //<=====
                {
                    foreach (var row in _cbbrok.Rows) //<=====
                    {
                        if (!row.IsFilteredOut) //<=====
                        {
                            e.Cell.Row.Cells["CLEARING_BROKER"].Value = row.Cells["COUNTERPARTY_ID"].Value; //<=====
                            break;
                        }
                    }
                 
                }
            }
        }
