根据列表框选择XAML / PowerShell

分类：编程问答

如何解决根据列表框选择XAML / PowerShell

我一直在论坛上浏览过许多类似的问题，但是没有一个问题使我真正到达需要的地方。

背景。

我正在Visual Studio中构建一个简单的UI以执行一些简单的任务，然后将XAML代码提取到Powershell中，以执行“操作”。这种选择是使解决方案远离基于客户要求的代码。

我希望使用包含3个值的列表框。有一个与此对应的文本框，它基于文本框中选择的项目，我希望它显示一个单独的电话号码。

现在我已经尝试过多次攻击，从提供xml文件到尝试组合框。我已经将它在VS中工作并编译为exe，但是当我将XAML代码移至Powershell时，由于缺少缺少的组件而导致失败。

我认为这可能是对我的操作方式的限制，所以我尝试简化并将其保存在纯XAML中。

我似乎找不到列表框和文本框的正确组合来定义它。

简单的例子...

列表框中包含

伦敦 曼彻斯特 利兹

选择列表框项目后，文本框将使用单独的电话号码更新。

我不是要在VS中寻找代码来做到这一点，它需要完全在xaml中定义，并且可以提升到Powershell中。

解决方法

我的英语不太好，我希望我能正确理解你。 您的设计看起来真的很棒，我只是用组合框替换了列表框，它更合适。但是，欢迎您再次使用列表框，它的工作方式相同。

这是一个不仅包含xml的解决方案，而且它以这种方式工作。 如果您需要XMLOnly解决方案，则还需要Powershell和数据绑定中的列表，但是目前我不知道数据绑定是否适用于Powershell。

让我知道我的解决方案是否有问题
