Zunächst einmal bin ich ein Amateur-und Nicht-Englisch-Muttersprachler, so würde ich es begrüßen, wenn Sie ein wenig Geduld mit mir haben würde;)TabControl geerbt Custom zeigt nichts
eine andere Frage Stackoverflow Nach Ich habe ein TabControl erstellt, das sich selbst erweitert (wie ein Expander), indem es nur die Vorlage des ursprünglichen TabControls ändert, sodass ich einfach die Höhe des Steuerelements ändern kann, wenn ein Tab ausgewählt ist.
Das funktionierte perfekt, aber einige ViewModel-Eigenschaften für die Logik benötigt. Jetzt muss ich diese Kontrolle wieder verwenden und ich dachte, der bessere Weg wäre, ein CustomControl zu machen.
Das Problem, das ich habe, ist, dass die Custom sind nur lookless, sind nicht Stil angewendet, obwohl ich Stile für sie in der Generic.xaml Datei angegeben haben, und die Build Action Eigenschaft Page, überarbeitet die AsemblyInfo.cs, und verwendet die DefaultStyleKeyProperty.OverrideMetadata im statischen Konstruktor. Alle folgenden weiteren Fragenvorschläge.
Ich denke, es wäre besser, den Code zu zeigen, den ich habe, und zu erklären, was ich mehr versucht habe, muss ich sagen, dass ich die Logik geschrieben habe, als ich das bemerkte, so dass es jetzt nicht funktioniert .

Und ein wenig MainWindow.xaml zum Testen:
<Window x:Class="PRUEBA_TABBEDEXPANDER.MainWindow"

<Grid>
<local:TabbedExpander TabStripPlacement="Top">
<TabItem Header="prueba1">
<TextBox Text="prueba1"/>
</TabItem>
</local:TabbedExpander>
</Grid>
Das ist mein letzter Versuch ist, mein erster Versuch die TabbedExpanderTabControlStyle Stil direkt an die individuelle Steuerung der Änderung anzuwenden war nur die TargetType, dann ohne habe ich versucht, die ItemsSProperty Zugabe, sondern nur die s TabControl‘mit vererbten ItemsSource mit der gleichen Syntax in dem 'MainWindow.xaml` und zum Ändern der Syntax:
<Grid>
<local:TabbedExpander TabStripPlacement="Top">
<local:TabbedExpander.ItemsS>
<TabItem Header="prueba1">
<TextBox Text="prueba1"/>
</TabItem>
</local:TabbedExpander.ItemsS>
</local:TabbedExpander>
</Grid>
Neben <local:TabbedExpander.Items> versuchen, die TabControl zu verwenden' s geerbt Items.
Das einzige, was arbeitete, war die Generic.xaml als ResourceDictionary und gilt TabbedExpanderTabControlStyle direkt an die individuellen Steuerung zu verschmelzen ..., die ich nehme an ist nicht der richtige Weg, es zu tun ... nicht wahr? Weil ich den Stil auf jedem kundenspezifischen Steuerelement anwenden müsste, das ich meiner Anwendung hinzufügen würde ...
Ich nehme an, dass ich entweder etwas falsch mache, indem ich den Stil anwende, oder die tabitems Sammlungen benutze, aber gerade jetzt ' ? m aus Ideen :(
Jede Idee
Die Sache ist die, dass, korrigieren Sie mich, wenn ich falsch, wenn ich tun, wenn ich fügt das benutzerdefinierte Steuerelement der App hinzu Ich muss den Stil manuell auf alle Instanzen anwenden, richtig? – Nox
Entschuldigung, ich drückte Enter, ohne den Kommentar zu beenden ¬¬ ... Ich dachte, dass mit benutzerdefinierten Steuerelementen der Stil automatisch auf alle Instanzen angewendet würde, also sollte ich den Weg finden, dies zu tun. – Nox
Sollte nicht, nein. Wenn Sie keinen Schlüssel angeben, erben alle untergeordneten Elemente des Zieltyps den Stil. – Joe
