General UI & DI Issues

Question

Hi All,
I need some advice/confirmation on some issues I am noticing when using the UI and DI.
1. Populating matrix from a query. If the data for a matrix is sourced from multiple tables, there is no other option than using a recordset and looping through the results setting the user datasources and then adding a new row to the matrix is there?
2. Combo Box - is there a way to not show the value, i.e I only want the description to display, but to use the value.
3. Adding buttons to system forms. I capture the et_FORM_LOAD event and add the button, Is there a reason why this dramatically slows down the loading of system forms? it is currently taking on average 3 seconds from the click event till the activate event, is this normal?
The reason I ask is my client is a bit concerned with the speed.
Thanks

Thanks for the response
1. I have had a look at that thread (and the one it references) - but I would prefer not to create temp tables and such - concurrency issues and having temp tables floating round can affect overall system performance, and that won't let me add blank rows between groups of data either.
2. I didn't think I was missing anything obvious, I will let the client know that I cannot change this behaviour.
3. For the button I am filtering the events like this:
private void app_ItemEvent(string formUID, ref SAPbouiCOM.ItemEvent pVal, out bool bubbleEvent)
#if DEBUG
     Trace.WriteLine(DateTime.Now + " " + pVal.BeforeAction + " " + formUID + ", " + pVal.FormTypeEx + " - " + pVal.ItemUID + ":" + pVal.EventType);
#endif
     bubbleEvent = true;
     if ((pVal.FormTypeEx == "150") && (!pVal.BeforeAction) && ((pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_LOAD)/* ||(pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_RESIZE)*/))
          if (!pVal.BeforeAction)
               AddMoveVehicleButton(formUID);
     else if (((pVal.FormTypeEx == "149") ||(pVal.FormTypeEx == "139") ||
                    (pVal.FormTypeEx == "133") ||(pVal.FormTypeEx == "142") ||(pVal.FormTypeEx == "143")) && (!pVal.BeforeAction) && ((pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_LOAD)/* ||(pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_RESIZE)*/))
          if (!pVal.BeforeAction)
               AddMovePartsCatalogButton(formUID);
               AddMoveFindButton(formUID);
     else if ((pVal.FormTypeEx == "150") && (!pVal.BeforeAction) && (pVal.ItemUID == "btnVehicle") && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED))
          OpenAssignVehicle(formUID);
     else if (((pVal.FormTypeEx == "149") ||(pVal.FormTypeEx == "139") ||
          (pVal.FormTypeEx == "133") ||(pVal.FormTypeEx == "142") ||(pVal.FormTypeEx == "143")) && (!pVal.BeforeAction) && (pVal.ItemUID == "btnFind") && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED))
          OpenFindPhone(pVal.FormTypeEx, formUID);
     else if (((pVal.FormTypeEx == "149") ||(pVal.FormTypeEx == "139") ||
          (pVal.FormTypeEx == "133") ||(pVal.FormTypeEx == "142") ||(pVal.FormTypeEx == "143")) && (!pVal.BeforeAction) && (pVal.ItemUID == "btnCat") && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED))
          OpenPartsCat(formUID);
     else if ((formUID == "frmPartsMan") && (_PartsMan != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          _PartsMan = null;
     else if ((formUID == "frmDefMan") && (_DefMan != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          _DefMan = null;
     else if ((formUID == "frmDefMod") && (_DefMod != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          _DefMod = null;
     else if ((formUID == "frmDefYear") && (_DefYear != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          _DefYear = null;
     else if ((formUID == "frmItemVeh") && (_ItemVeh != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          _ItemVeh = null;
     else if ((formUID == "frmFindPhone") && (_FindPhone != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          if (_FindPhone.SelectedBusinessPartner != null)
               FindRecord(_FindPhone.SourceForm, _FindPhone.SelectedBusinessPartner);
          _FindPhone = null;
     else if ((formUID == "frmSelPart") && (_SelPart != null) && (!pVal.BeforeAction) && (pVal.EventType == SAPbouiCOM.BoEventTypes.et_FORM_CLOSE))
          if (_SelPart.SelectedIDs != null)
               SelectParts(_SelPart.SourceForm, _SelPart.SelectedIDs);
          _SelPart = null;
Is this enough or should I somehow filter more?
