Post subject: | DBGridEh - Use backspace key with Dropdownbox |
Good morning, We sometimes use the DropDownBox included in the TDBGridEh component because it is much more flexible and powerful than the picklist (data refresh, multi-column display, search, etc.). However, we encounter a problem that may be related to misuse on our part. Our users have found that they can choose from the drop-down list, or enter a value directly on the keyboard. However, if they made an entry error (typing error), the backspace key does not work. They are forced to select the contents of the cell with the mouse and use the Delete key on the keyboard. Do you know what is due? We think this is a property but we did not find it. Knowing that the property of the 'LimitTextToListValue' column is False. Thanking you in advance, ------------------- Bonjour, Nous utilisons parfois le DropDownBox inclus dans le composant TDBGridEh car cela est bien plus souple et plus puissant que la picklist (actualisation des données, affichage multi colonnes, recherche, etc.). Cependant, nous rencontrons un problème qui est peut être lié à une mauvaise utilisation de notre part. Nos utilisateurs ont constaté qu'ils peuvent choisir dans la liste déroulante, ou saisir directement une valeur au clavier. Par contre, s'ils ont fait une erreur de saisie (faute de frappe), la touche retour arrière ne fonctionne pas. Ils sont obligés de sélectionner le contenu de la cellule avec la souris et d'utiliser la touche Supprimer du clavier. Savez-vous à quoi cela est dû ? Nous pensons qu'il s'agit d'une propriété mais nous n'avons pas trouvé. Sachant que la propriété de la colonne 'LimitTextToListValue' est à False. En vous remerciant par avance, |

Hello To understand the problem we need to reproduce the same situation on our computer. Can you send a Demo project or provide an remote access to your computer? |

Hello This is because, by default, the combobox does not allow entering text that is not in the list of values in the drop-down list. Set Column.LimitTextToListValues = False and the combobox will behave more like the behavior of a simple text editor. |

Hi, First, I wish you a Happy New Year !!! Thanks for your feedback however the property Column.LimitTextToListValues is already False (default value). We know this property and we never use it. The behavior is identical. Thanks, |

Hello Can you send dfm+pas file to support@ehlib.com or simple Demo project. I don't see if you use lookup relations in the column or not. |

Good morning, we bought "renew annual update" wednesday and we downloaded a new version (today) and we use dropdownbox but we have an error when used backspaced Quote: QueryPicklistRecept: Champ '' non trouvé In english, i think : Quote: QueryPicklistRecept: Field '' not found QueryPicklistRecept is TADOQuery (cf. screenshots 21/12/2018). is a change necessary in the code compared to the old version? Thank you in advance, |

Hello On one of your screens I see the next assignment Quote: DropDownBox.ListFieldNames = CDE_PROD;LIB_30; Try to remove last ";" in the assignment. VCL parses it as three fields: "CDE_PROD", "LIB_30", and "" (Empty) |
