通过DataTemplates和ContentControl绑定属性 [英] Binding properties through DataTemplates and ContentControl

问题描述

我喜欢这个答案，而且几乎适合我。

但是，如果我的 DataTemplate 在外部 ResourceDictionary ？

But, how can I achieve this if my DataTemplate is in a external ResourceDictionary?

我正在使用Prism，我为每个模块提供了 DataTemplates （用于通用CRUD视图）通过使用这样的文件：

I'm using Prism and I provide the DataTemplates (for generic CRUD views) by each module, by using files like this:

<ResourceDictionary ... some hidden ns here ... >
    <DataTemplate DataType="{x:Type model:Operation}">
        <vw:OperationView />
    </DataTemplate>
    <DataTemplate DataType="{x:Type model:Customer}">
        <vw:CustomerView />
    </DataTemplate>
</ResourceDictionary>

然后我使用这个答案将 ResourceDictionaries 合并到Shell应用程序中，我有一个默认的CRUD视图，它具有以下代码：

Then I use this answer to merge the ResourceDictionaries into the Shell app and I have a default CRUD view which has that code:

<ContentControl Content="{Binding MyGenericObject}" />

ContentControl 自动拉出正确的视图。它的工作正常，但我想知道在每个视图中绑定对象的属性。

That ContentControl automatically pull the correct view. It's working fine, but I want to know bind the property of the objects in each view.

这是这些视图（OperationView.xaml）的示例：

That's a sample of these views (OperationView.xaml):

<UserControl x:Class="TryERP2.Cadastro.View.OperationView"
             ... some hidden NS ... >
    <StackPanel>
        <Label Content="Id" />
        <TextBox Text="{Binding ????WHAT????}" />
        <Label Content="Description" />
        <TextBox Text="{Binding ????WHAT????}" />
    </StackPanel>
</UserControl>

如何绑定这些属性？

推荐答案

由于 DataContext 后面的 OperationView 将是一个类型为操作，然后您只需绑定到操作上的任何属性

Since the DataContext behind OperationView will be an object of type Operation, then you simply bind to whatever property on Operation you want

<!-- DataContext will be model:Operation per your DataTemplate -->
<UserControl x:Class="TryERP2.Cadastro.View.OperationView"
             ... some hidden NS ... >
    <StackPanel>
        <Label Content="Id" />
        <TextBox Text="{Binding Id}" />
        <Label Content="Description" />
        <TextBox Text="{Binding Description}" />
    </StackPanel>
</UserControl>
