在DataTemplate中为MenuItem指定命令 [英] Specify Command for MenuItem in a DataTemplate

问题描述

我有一个上下文菜单。它绑定到一些集合，它有一个定义的ItemTemplate，像这样：

I have a context menu. It's bound to some collection and it has a defined ItemTemplate like this:

<ContextMenu
    ItemsSource={Binding ...}
    ItemTemplate={StaticResource itemTemplate}
    />

itemTemplate是一个带有TextBlock的简单DataTemplate：

itemTemplate is a simple DataTemplate with a TextBlock:

<DataTemplate x:Key="itemTemplate">
    <TextBlock Text={Binding ...} />
</DataTemplate>

如何将MenuItem的Command属性绑定到底层对象的属性？

How do I bind Command property for MenuItem to the underlying object's property?

推荐答案

我想你需要将你的TextBlock包装在一个MenuItem中：

I think you need to wrap your TextBlock in a MenuItem:

<DataTemplate x:Key="itemTemplate">
    <MenuItem Command={Binding ...}>
        <TextBlock Text={Binding ...} />
    </MenuItem>
</DataTemplate>

但我现在没有一个IDE在我面前试试这个。让我知道它是怎么回事。

But I don't have an IDE in front of me right now to try this. Let me know how it goes.

看起来你需要使用ItemContainerStyle，如下所示此处。对不起，引导你开始错误的路径，但我在一个IDE的前面，这工作：

Looks like you need to use the ItemContainerStyle as seen here. Sorry for leading you down the wrong path at the start there - but I got in front of an IDE and this works:

<ContextMenu.ItemContainerStyle>
    <Style TargetType="MenuItem">
        <Setter Property="Command" Value="{Binding ...}"/>
    </Style>
</ContextMenu.ItemContainerStyle>
