MVVM 焦点到文本框 [英] MVVM Focus To Textbox

问题描述

如何将焦点设置到 TextBox 而不指定 TextBox 的名称?目前我正在做以下事情

How would I set focus to a TextBox without specifying the name for that TextBox? At the moment I am doing the following

<Window FocusManager.FocusedElement="{Binding ElementName=Username}">
    <Grid>
        <TextBox Text="{Binding Username}" Name="Username" />            
    </Grid>
</Window>

是否有任何方法可以在不为 TextBox 指定名称的情况下执行此操作.我相信 MVVM 有一个 Name 元素通常意味着糟糕的设计?

Is there any way of doing this without specifying a Name for the TextBox. As I believe in MVVM having a Name element usually means bad design?

推荐答案

我在对 类似的问题.该解决方案涉及使用附加属性和一个框架，用于将接口命令从 ViewModel 传递回视图.
