"Sorin H" | Hello Tim
I try to isolate only the parts that demonstrate the problem. The problem is that on the dbgrid the lookupField "LkpRepairDtl" is blank in spite of the fact that the field "RepairDtlId" have values. Thanks for the support Sorin Attachments: Unit2.pas Unit2.dfm |

That will never work. I can see tbCarRepair.Open; but there's no open statement for the other table. Roy Lambert [Team Elevate] |

Thanks 1 I thought that tables that are used only for lookup fields are open auto. and the values from tbTblRepair table indeed appear on the dbgrid. 2 For safety I open all the tables but the same problem remain.

<< The app have a company table with company name, city and street. The cities and street come from 2 tables that have m/d relation. I want to insert a record write the company name, select the city and select the street that belong to the selected city. >> The problem is that you are expecting a lookup field to move the record pointer in the target lookup table, which is not the case. A lookup simply does the lookup and leaves the current record pointer intact. What you want to do instead is make the fields calculated fields, and perform the lookup by using FindKey/Locate in an OnCalcFields event handler. procedure TForm2.tbCompanyCalcFields(DataSet: TDataSet); begin if tbCity.Locate('ID',tbCompanyCityID.AsString,[]) then tbCompanyLkpCity.AsString:=tbCityCity.AsString else tbCompanyLkpCity.AsString:='Not found'; if tbStreet.Locate('ID',tbCompanyStreetID.AsString,[]) then tbCompanyLkpStreet.AsString:=tbStreetStreet.AsString else tbCompanyLkpStreet.AsString:='Not found'; end; -- Tim Young Elevate Software www.elevatesoft.com |
