Zentrierung DatePicker-Steuerelement

Bin ich mit dem datepicker-Steuerelement von der wpf-toolkit. Ich muss center richten Sie den Inhalt in datepicker-Steuerelement. Wie kann ich das erreichen?

Versucht VerticalContentAlignment="Center". Es hat nicht funktioniert.

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

Funktioniert für .Net 4 ist DatePicker.

Keine der anderen Lösungen arbeiten wird, weil die vertikale Ausrichtung des DatePicker-Inhalte (text-und button) ist hart codiert in der Standard-WPF-Stil. d.h. die Standard-WPF-DatePicker-Stil wurde nicht in einer Weise geschrieben, wobei die vertikale Ausrichtung (unter vielen anderen Eigenschaften) überschrieben werden können.

Dieses Problem beheben sollte (vertikale Ausrichtungen wurden Vorlage begrenzt)
- extrahieren Sie die Standard-DatePicker-Stil
befestigen Sie den Stil mit der entsprechenden template-Bindungen
- wenden Sie den neuen Stil

<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>

Erstellen ControlTemplate für den DatePicker und den Satz "VerticalContentAlignment" - Eigenschaft der PART_TextBox element "Center".

InformationsquelleAutor andy369

Gehören dieses Stück code in die Ressourcen der übergeordneten Steuerung:

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

Hatte ich ein bisschen ein Problem, immer die Taste auf der rechten Seite des DatePicker korrekt ausgerichtet sind, aber das funktionierte:

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