Question

我的Silverlight表单需要为3个类的对象中的字段输入值，这些字段将共同调用Web服务的请求

GUI的代码正在进行中

如你所见，在网格中我有几个字段，都是必需的（txtCodiceFiscale是16个字母数字字符长）。我的服务参考定义了3个主要类：Persona（人）Documento（文档）和StrutturaSanitaria（HealthFacility）。阅读我发现执行验证的“更好”方式是使用数据绑定（我可以在经典的WinForms中轻松完成），也许它与MVVM模式有关，我还没有掌握。< / p>

我了解到，不是让表单按钮的Click事件手动验证代码，而是以传统方式将表单及其文本框绑定到数据上下文对象的属性。

问题

我需要3个数据对象。到目前为止我找到的所有示例都只显示了一个分配给根控件的对象（在我的情况下，我需要将对象绑定到第一个TabItem，因为第二个选项卡应该显示来自Web服务的结果，并且将被合理地绑定）。是否可以将控件绑定到多个对象？（我不知道指定多个数据对象的语法）如果没有，我至少可以将它绑定到这样的类并引用树中的每个属性吗？

public class DataContainer {
    public Persona Persona{get; set;}
    public Documento Documento {get; set;}
    public StrutturaSanitaria Struttura {get; set;}
}

这让我省去了定义一个体现所有值的类的麻烦，所以至少当我点击Submit时，我所有的对象都充满了数据。

或者，您是否有其他可行的解决方案，代码便宜？我正试图找一些书，但我没有时间在截止日期之前阅读。有人能给我一个关于数据验证的好教程，帮助我理解背后的机制，或者简单地向我解释一下吗？

Answer 1

Colin Eberhardt几年前在Silverlight上发表了一篇关于multiple binding的博客文章。也许这会有所帮助吗？

这基本上与WPF MultiBinding类中应用的方法相同。

Silverlight中的数据验证具有多个对象
