    Programmatically set DBLookupComboBox item with RemoteQuery

    in General

    Posted

    How can i set KeyValue to load text of an item on UniDBLookupComboBox when it is with the property "RemoteQuery" set to "True"? When i use a Data Source linked to the "ListSource" this works perfectly. But when i try to do using RemoteQuery, the UniDBLookupComboBox field doesn't display the selected item.

    I tried to run manually the event to force item load: 

    UniDBLookupComboBoxEmployeeRemoteQuery('My item value', UniDBLookupComboBoxEmployee.Items);
UniDBLookupComboBoxEmployee.KeyValue := 'My item value';

    But it doesn't work, the field keeps empty.

    How to reproduce: Add a button to "DBLookupComboBox - Custom Remote Query" example and in the "OnClick" event try to select an item like: 

    UniDBLookupComboBox1.KeyValue := 1651; // or [].Text := '1651';

    Same problem here.. I'm using trial version 1.90 (latest disponible). 

    
UniDBLookupComboBoxBank.ListSource := FBankController.ReturnDataSource;

// Other settings are on .dfm, and it show properly all itens from the database

UniDBLookupComboBoxBank.KeyValue := FBankEntity.ID;

// It makes no change at all. The KeyField on the component is correct, the record exists, the ID is correct...

    I need this to complete my tests on the framework to consider buying it.

    I found what i was doing wrong...

    The "KeyValue" field should be set when the "TUniDBLookupComboBox" is fully loaded. I changed the event "OnShow" for "OnReady" and it worked.
