Question

我的控件是由嵌套列表框和树视图构成的。每个列表框/树视图项还包含富文本框和其他控件。

我想定义一个'标签'焦点行为，这样当用户点击'Tab'时，下一个可聚焦项目（根据我定义的顺序）将变得集中。

目前它不起作用，因为我接受（它只能部分工作）。

我的问题不是针对我的情况而是针对如何定义这种行为。作为一个极端的例子，假设我想完全控制它并使焦点跳到物理上不接近的物品之间。

任何人都可能知道如何控制它？

乔，这个机制比我想象的更聪明，检查这个嵌套 - 它完美地运作：

<ListBox KeyboardNavigation.TabNavigation="Continue">
    <ListBoxItem Focusable="False">
        <ListBox KeyboardNavigation.TabNavigation="Continue">
            <ListBox.Items>
