은색 텍스트 상자에 세로 내용 맞춤을 설정하는 방법

Question

모든 텍스트를 가운데에 정렬하는 실버 라이트 텍스트 상자가 있습니다. VerticalContentAlignment가 작동하지 않습니다! 텍스트가 가운데에서가 아니라 맨 위에서 시작되도록이 텍스트를 정렬하는 방법은 무엇입니까?

<StackPanel> 
    <TextBox Text="{Binding OverView,Mode=TwoWay}" AcceptsReturn="True" 
    Loaded="Update_EditableState" 
    Height="135" HorizontalAlignment="Left" 
    TextWrapping="Wrap" Width="200"> 
    </TextBox> 
</StackPanel> 

Answer 1

마찬가지로 Microsoft documentation 기준 텍스트 입력란의 기본 템플릿에서는 VerticalContentAlignment가 작동하지 않습니다.

해결하려면 우리 자신의 스타일이 필요합니다. 템플릿의 verticalcontentalignment에 바인딩 verticalalignment를 추가하면 문제가 해결되었습니다.

여기에 내가 표준 텍스트 상자 스타일 여기

<ScrollViewer x:Name="ContentElement" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/>
