为什么在 ScrollViewer 内部单击时我的 TextBox 会聚焦? [英] Why does my TextBox get focused when clicking inside of ScrollViewer?

问题描述

在我的 Windows Store 应用程序中，我创建了一个 ScrollViewer(里面有一个 Grid)，里面有几个 TextBox.每当用户单击 ScrollViewer 中的任意位置时，第一个 TextBox 就会获得焦点.我不知道为什么会发生这种情况，这肯定不是我想要的行为.

In my Windows Store app, I've created a ScrollViewer (with a Grid inside) with a few TextBoxes inside. Whenever the user clicks anywhere within the ScrollViewer, the first TextBox is focused. I have no idea why this happens, and it certainly is not the behavior I want.

这只是 XAML 试图有用"的一种症状吗?我该如何预防?

Is this just a symptom of XAML trying to be "helpful"? How do I prevent it?

编辑:我找到了线索.这仅在我的 TextBox 位于 ScrollViewer 内时发生.它也出现在 C++ 和 C# 项目中，因此它显然是 XAML/WinRT 的症状.添加示例 XAML:

Edit: I found a clue. This only occurs when my TextBoxes are inside of a ScrollViewer. It also occurs on both C++ and C# projects, so it's obviously a symptom of XAML/WinRT. Adding example XAML:

使用以下 XAML，如果我聚焦第二个 TextBox，然后单击框之间边距中的任意位置，第一个 TextBox 将自动聚焦.我不想让它集中注意力.

With the following XAML, if I focus the second TextBox and then click anywhere in the margin between the boxes, the first TextBox is automatically focused. I don't want it to be focused.

<ScrollViewer Background="#111111"
              VerticalScrollBarVisibility="Auto">
  <Grid>
    <Grid.RowDefinitions>
      <RowDefinition />
      <RowDefinition />
      <RowDefinition />
    </Grid.RowDefinitions>

    <TextBox Grid.Row="0" />
    <TextBox Grid.Row="1" />
  </Grid>
</ScrollViewer>
