How to get a combo box to trigger another combo box?

You can try using dataview information before dropdown, or you can use special filtering syntax in the properties window of dropdowns, but I don’t remember it. I think that’s Epicor documented somewhere

private void epiComboC2_BeforeDropDown(object sender, System.ComponentModel.CancelEventArgs args)
                {
                                // ** Place Event Handling Code Here **
                                                                EpiDataView edv = oTrans.Factory("Contact");
                                                                
                                                                epiComboC2.Rows.ColumnFilters["CodeID"].FilterConditions.Clear();
                                                                epiComboC2.Rows.ColumnFilters["CodeID"].FilterConditions.Add(Infragistics.Win.UltraWinGrid.FilterComparisionOperator.StartsWith,edv.dataView[edv.Row]["ShortChar03"]);
                                                                
                }
