Ändern Sie die Bilder auf Benutzerdefinierte Kontrollkästchen in WPF

Wie bereits erwähnt @HighCore die Notwendigkeit für die Fähigkeit, Vektor-Grafiken. In diesem Fall verwenden Sie die Path, wo in Data zu den angegebenen Koordinaten, auf dem das Objekt gezeichnet (MSDN).

Vorteile:

• Speichern Sie es nicht in den Akten, kleinere Größe

• Dynamisch ändern von Farbe, Größe und die ganze Form

Nachteile (meiner Meinung nach):

• Können Sie nicht immer den richtigen Data für die Path

Etwa minus: Es gibt spezielle Websites (http://www.modernuiicons.com) und Programme für die Konvertierung das Bild zu Data.

Ändern Sie den Stil des CheckBox mit der Path:

Using

<StackPanel Orientation="Vertical" HorizontalAlignment="Center">
    <CheckBox Height="35"
              Style="{StaticResource styleCustomCheckBox}" 
              Content="MySolution1" />

    <CheckBox Height="35"
              Style="{StaticResource styleCustomCheckBox}" 
              Content="MySolution2" />
</StackPanel>

Output

Können wir auch speichern Path's in Ressourcen und beziehen sich auf Sie als wie dies:

<Path x:Key="MyPath" Data="F1 M 38,19C 48.4934,19 57,27.5066 ... />

...

<Setter TargetName="MainPath" Property="Data"
        Value="{Binding Source={StaticResource MyPath}, Path=Data}" />

Edit

Angeben, beliebige Symbole, ich habe zwei beigefügten dependency properties (string-Typ):

• IsCheckedOnData

• IsCheckedOffData

IsCheckedOnData enthält Data Wert von IsChecked = "True", IsCheckedOffData Wert von IsChecked = "False".

Nun müssen Sie nur, um zu bestimmen, die Zeichenfolgen von Symbolen und definieren, wie eine Ressource (zum Beispiel).

Note: Im Stil, den ich nicht verwendet habe TemplateBinding weil TemplateBinding funktioniert nicht außerhalb einer Vorlage oder außerhalb seiner VisualTree Eigenschaft, so können Sie nicht einmal mit TemplateBinding innerhalb einer Vorlage-Auslöser. Daher müssen wir mit dem Bau {RelativeSource TemplatedParent} und ein Path gleich die Abhängigkeit Eigenschaft, dessen Wert Sie abrufen möchten.
