问题描述

我想在一个应用程序,不同的页面的TabItems使用MVVM。

I want to use MVVM in an application where the different pages are TabItems.

为此,我使用一个观察的集合我的视图模型(项目),并将其绑定到的ItemSource的TabControls

For this I use an observable collection of my view models (Items) and bind it to the tabcontrols ItemSource.

对于每个视图模型,我创建了一个单独的数据模板来呈现这样的正确的观点:

For each view model, I created an individual data template to render the correct view like this:

<DataTemplate DataType="{x:Type baseVm:AViewModel}">
  <baseVw:AView /> 
</DataTemplate>

要在标签的标题显示正确的名字,我创建了另一个数据模板应用到每个标签控件的元素:

To display the correct name in the tab's header I created another data template to be applied to each of the tab control's elements:

<DataTemplate x:Key="ViewModelTabTemplate">
  <DockPanel>
    <ContentPresenter Content="{Binding Path=Name}"/>
  </DockPanel>
</DataTemplate>

标签控件看起来是这样的:

The tab control looks like this:

<TabControl x:Name="myTabControl" 
            ItemsSource="{Binding Items}" 
            ItemTemplate="{DynamicResource ViewModelTabTemplate}">
</TabControl>

我想现在要做的就是从包含集合视图模型内启用/禁用标签。视图模型的基类包含一个依赖属性IsEnabled,我想这个绑定的意见。如果我直接在这样的观点做到这一点:

What I want to do now is to enable/disable tabs from within the view model that contains the collection. The view model's base class contains a dependency property IsEnabled and I would like to bind this to the views. If I do this directly in the view like this:

IsEnabled="{Binding IsEnabled, FallbackValue=true}"

当我打开IsEnabled属性设置为false标签页的内容被禁用。但我真正想要的是也是禁用的TabPage的标签,而不仅仅是内容。

the tab page's content gets disabled when I turn the IsEnabled property to false. But what I really want is to also disable the tabpage's tab and not just the content.

感谢您的帮助!

推荐答案

也许你可以尝试这样的事情 -

Maybe you could try something like this -

<TabControl>
    <TabControl.ItemContainerStyle>
        <Style TargetType="{x:Type TabItem}">
             <Setter Property="IsEnabled" Value="{Binding IsEnabled}"/>        
        </Style>
    </TabControl.ItemContainerStyle>
</TabControl>
