Question

我有一个带有2个标签的窗口，每个标签包含一个具有相同属性的Scrollviewer

<ScrollViewer VerticalScrollBarVisibility="Auto"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CanContentScroll="False">
    <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
    </Grid>
</ScrollViewer>

现在差异：

第一个标签：

网格行0包含一个<WrapPanel>，内部有<StackPanel>个所有控件

网格行1包含<DataGrid>，填充其余部分并具有最小高度

第二个标签：

网格行0包含一个WrapPanel，内部有<DockPanel>个所有控件

网格行1包含<DataGrid>，填充其余部分并具有最小高度

问题：

当我打开窗口时，有太多的控件无法一次查看所以滚动条或<ScrollViewer>出现，这是完美的。但由于某些尴尬的原因，第二个标签滚动条不在顶部，而是在窗口下方略超过3/4。我想知道以前是否有人讨论过这个问题并且可能知道我忘记了什么？

我尝试了什么：

将有问题的<ScrollViewer>命名并调用表单加载MyScroll.ScrollToTop();无法正常工作，但我想这是因为控件尚不存在。
我尝试将GotFocus事件添加到<TabItem>但每次我点击其中的控件时都会触发此宝贝。当我第一次点击窗口尽头的<ComboBox>时，我发现这很有趣。

在尝试了所有我发现在<ScrollViewer>被拳头查看时从头顶开始是我想要的，并想知道是否有办法做到这一点或我是否遗漏了什么。

其次我实际上希望<ScrollViewer>滚动到顶部，当人们导航<TabItem>时，我的小错误让我意识到我真的喜欢它。

用户很少会在该窗口上使用超过2个选项卡，因此不需要疯狂的解决方案

编辑：我找到了一些东西。如果我向上滚动我有问题的选项卡，然后再选择另一个选项卡并回来，滚动返回到它被窃听的地方。

请注意，对于选定的组合框和文本框的值，只有简单的绑定，我没有任何事件。 o是和网格的数据源，但此时两个标签都是空的。

我有4个窗口，格式相同，12个窗口中只有1个。

Answer 1

解决方案是修改XAML的编写顺序。 WPF将焦点放在XAML代码中的第一个元素，无论它是否是最后一个元素

WPF Scrollviewer的起始位置很奇怪
