Центрирование элемента управления DatePicker

5 голосов
/ 07 октября 2009

Я использую элемент управления datepicker из инструментария wpf. Мне нужно выровнять содержимое по центру в элементе управления datepicker. Как мне этого добиться?

Tried VerticalContentAlignment = "Центр". Это не сработало.

<Style TargetType="DatePickerTextBox">
    <Setter Property="VerticalAlignment" Value="Center" />
    <Setter Property="Padding" Value="2" />
</Style>

Ни одно из других решений не будет работать, поскольку вертикальное выравнивание содержимого DatePicker (текст и кнопка) жестко задано в стиле WPF по умолчанию. то есть стиль DateFicker WPF по умолчанию не был написан так, чтобы вертикальное выравнивание (среди многих других свойств) могло быть переопределено.

Это должно исправить (вертикальные выравнивания были ограничены шаблоном) - извлечь стиль DatePicker по умолчанию - исправить стиль, чтобы использовать соответствующие привязки шаблона - применить новый стиль 

<Style TargetType="DatePicker" BasedOn="{StaticResource DatePickerStyle.Centred}">
    <Setter Property="FontSize" Value="16" />
    <Setter Property="Height" Value="128" />
    <Setter Property="VerticalAlignment" Value="Center" />
    <Setter Property="VerticalContentAlignment" Value="Center" />
</Style>

Включить этот фрагмент кода в Ресурсы родительского контроля: 

<Style TargetType="{x:Type DatePickerTextBox}">
    <Setter Property="VerticalContentAlignment" Value="Center" />
</Style>

У меня была небольшая проблема с правильной настройкой кнопки справа от DatePicker, но это сработало: 

<my:DatePicker>
    <my:DatePicker.Resources>
        <Style TargetType="Button">
            <Setter Property="VerticalAlignment" Value="Top"/>
        </Style>
    </my:DatePicker.Resources>
</my:DatePicker>

Создайте ControlTemplate для DatePicker и установите для свойства «VerticalContentAlignment» элемента PART_TextBox значение «Center».
