Captions

Captions sind für den User gedachte Beschriftungen für verschiedene Sprachen. Sie werden in Objekten vom Typ DynamicString gespeichert.

Set a single value

Elements.Company
  .Caption("de-CH", "Firma")
  .Caption("fr-CH", "firme");

This is the recommended way to set captions.

Defining values for code elements

Quino includes support for decorating code elements (e.g. enums) with language-specific captions and for reading those captions at run-time.

The LanguageTextAttribute associates a string value with a language. Quino defines EnglishCaptionAttribute and GermanCaptionAttribute for convenience. Applications are free to define their own.

The example below shows how to use the attributes.

public static class StandardRights
{
  [GermanCaption("Lesen")]
  [EnglishCaption("Read")]
  public const string Read = "read";
}

Defining expressions for captions

If the caption depends on some other property an expression can be assigned to it. This currently only works for standard use-cases. It does not work in the following cases:

MultiLanguageProperty
List-Layouts
PluralCaption of a class

Elements.Company
  .CaptionExpression("de-CH", "Active ? 'Aktive Person' : 'Inaktiv'");
