Вопрос:
возможно, это глупый вопрос..
У меня есть AutoSuggestBox внутри StackPanel с другими объектами там:
<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>
Проблема в том, что текст внутри AutoSuggestBox находится сверху, а не по центру.
Я пробовал решение из других вопросов, в которых используется Style, но когда я использую Style (независимо от того, какое свойство я помещаю внутрь), он удаляет значок «найти», который я поместил в поле AutoSuggestBox
<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>
Когда я удаляю свойство «Strech», это выглядит еще хуже:
Я хочу, чтобы текст внутри AutoSuggestBox был в центре, а поле AutoSuggestBox располагалось вертикально на панели стека, и чтобы значок «Найти» сохранялся. Есть идеи? Спасибо
Ответ №1:
Для достижения вашей цели вам необходимо настроить ControlTemplate текстового поля в стиле AutoSuggestBox.
Вы могли бы легко использовать инструменты для работы с темами, чтобы найти стиль AutoSuggestBoxTextBoxStyle по умолчанию. Затем вы обнаружите, что существует ContentControl с именем ‘PlaceholderTextContentPresenter’. Он используется для отображения текста ‘Search Reg’. Вам нужно настроить VerticalAlignment="Center" , чтобы текст располагался по центру по вертикали.
Смотрите мой пример кода для справки:
<AutoSuggestBox x:Name="SearchBox" QueryIcon="Find" PlaceholderText="Search reg." VerticalAlignment="Stretch">
<AutoSuggestBox.TextBoxStyle>
<Style TargetType="TextBox">

Комментарии:
1. Привет, он помещает заполнитель в центр, но при вводе текста он находится сверху, я не смог найти, какое свойство отвечает за текст
2. @Izik Пожалуйста, найдите элемент управления ‘ScrollViewer’ с именем ‘ContentElement’ в стиле. Установите
VerticalAlignment="Center"для этого, чтобы решить эту проблему.3. Привет, спасибо! Я воспользовался вашим советом при редактировании ScrollViewer. Я сделал кое-что немного другое, создав 3 строки в сетке и поместив ScrollViewer в строку 1, это сработало.
