Question

这可能是一个愚蠢的问题。

我在StackPanel中有AutoSuggestBox，还有其他对象：

<StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Stretch">
        <ComboBox x:Name="BoardComboBox" PlaceholderText="Board" VerticalAlignment="Stretch"/>

        <AutoSuggestBox x:Name="SearchBox" QueryIcon="Find" PlaceholderText="Search reg   ." VerticalAlignment="Stretch">      
        </AutoSuggestBox>

        <Button>
            <StackPanel>
                <TextBlock Text="Load"/>
                <SymbolIcon Symbol="Document"/>
            </StackPanel>
        </Button>
            .....
 <StackPanel>

问题在于AutoSuggestBox内部的文本位于顶部，而不是居中。

我已经尝试了其他使用样式的问题的解决方案，但是当我使用样式（无论我放置在哪个属性中）时，它都会删除我在AutoSuggestBox中放置的“查找”图标

<AutoSuggestBox x:Name="SearchBox" QueryIcon="Find" PlaceholderText="Search reg   ." VerticalAlignment="Stretch" MinWidth="300">
        <AutoSuggestBox.TextBoxStyle>
            <Style TargetType="TextBox">
                <Setter Property="FontSize" Value="30"/>
            </Style>
        </AutoSuggestBox.TextBoxStyle>
</AutoSuggestBox>

当我删除“ Strech”属性时，它看起来更糟：

我希望AutoSuggestBox内的文本居中，并在StackPanel中垂直拉出AutoSuggestBox并保持“查找”图标。有任何想法吗？谢谢

要实现目标，您需要以AutoSuggestBox的样式自定义TextBox的ControlTemplate。

您可以按照Use tools to work with themes easily查找默认的AutoSuggestBoxTextBoxStyle。然后，您会发现有一个名为“ PlaceholderTextContentPresenter”的ContentControl。它用于显示“搜索注册表”文本。您需要为其设置VerticalAlignment="Center"，以使文本位于垂直中心。

请参阅我的代码示例以供参考：

 <AutoSuggestBox x:Name="SearchBox" QueryIcon="Find" PlaceholderText="Search reg." VerticalAlignment="Stretch">
            <AutoSuggestBox.TextBoxStyle>
                <Style TargetType="TextBox">
                    ....
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="TextBox">
