取决于ContentControl（Caliburn.Micro）的不同视图 [英] Different View depending on ContentControl (Caliburn.Micro)

问题描述

我将ViewModels绑定到ContentControls，让Caliburn负责创建和绑定视图。但是，我想根据我要绑定到的ContentControl来自定义Caliburns ViewModel-> View约定。

I'm binding ViewModels to ContentControls and letting Caliburn taking care of creating and binding the view. However, I would like to customize Caliburns ViewModel->View convention based on which ContentControl I'm binding to.

例如，一个常规的ContentControl，我想要一个常规的View绑定（SomethingViewModel-> SomethingView）。但是对于某些ContentControl，我希望Caliburn获取一个名为SomethingViewSpecial的视图。

For example, a regular ContentControl, I want the regular View to bind (SomethingViewModel -> SomethingView). But for a certain ContentControl, I want Caliburn to fetch a View named for example SomethingViewSpecial. Is that possible?

推荐答案

是的，有可能。

使用 cal：View.Context 附加属性，然后为指定的上下文命名视图，例如 YourNamespace.Something.ContextView （从视图模型名称中删除 ViewModel，添加一个点，以及Context属性的值）。

Use cal:View.Context attached property and then name your view for the specified context like YourNamespace.Something.ContextView (remove "ViewModel" from your view model name, add a dot, and the value of Context property).

那样，您甚至可以将多个视图绑定到一个视图模型。

By that, you can even bind several views to one view model.

示例：

<ContentControl x:Name="Toolbar" cal:View.Model="{Binding ActiveItem}" cal:View.Context="Toolbar" />

您可以看到工作示例此处（摘自 CoProject 示例应用程序，第9部分）。
