    uniDBLookupComboBox with new record

    I'm working with an evaluation copy of uniGUI. I'm having difficulty implementing a uniDBLookupComboBox. Link the uniDBLookupComboBox to a primary TDataset using the DataSource and DataField properties. Link the uniDBLookupComboBox to a lookup TDataset using the ListSource, KeyField and ListField properties. Open the respective datasets. Insert a new record into the primary TDataset. (This will result in an "empty" row.) This causes an EVariantTypeCastError exception. 'Could not convert variant of type (UnicodeString) into type (Integer)' I would appear that the uniDBLookupComboBox is attempting to Locate the corresponding lookup record using a null value from the primary dataset. Is there a way around this difficulty? Many thanks, MV

  5. Merhaba; UniDbLookupComboBox ile 245 veri ile bağlıyorum. Seçim yapmak istediğimde Çok fazla bekliyor ve sonrasında sayfa yanıt veremez duruma geliyor. 3-4 ay önceki versiyonda yine aynı sayıdaki veride bu işlemi sorunsuz çok hızlı yapabiliyordum Şimdi tesadüfen fark ettim. UniDbLookupComboBox tam verimli çalışabilmesi için max kayıt sayısı var mıdır veya bilmediğim bir ayarını turue veya false yapsak düzelir mi. Yardımlarınızı rica ederim. İyi çalışmalar.
  6. For those having problems allowing empty value or the selection of only items in list with incremental search in an editable DBLookupComboBox... (i was one too ) Add to the DBLookupCombobox -> ClientEvents -> ExtEvents -> OnAfterrender function OnAfterrender(sender){ sender.allowBlank=true; sender.editable = true;//This allows you to edit the DBLookupCombobox sender.forceSelection=true;//This line allows only item in list to be selected sender.beforeBlur= function(){ var value = this.getRawValue(); if(value == ''){ this.lastSelection = []; } this.doQueryTask.cancel(); this.assertValue(); } } I face a problem on setting null value to the coresponding field at server because the above trick does not set null value to field. I tryed and an ajax request to achieve the update.. but it keeps the last keyfieldvalue of the field.. if anyone can help
  7. Hi, i have a question about the UniDBLookupComboBox: Is it possible to manually/programmatically open the dropdown of the component? Like you simulate the press on it so it opens the dropdown list. Thanks.
