I'm loading xaml directly in C++/CX and I have a problem that I want to access the properties that are described on xaml and modify them. This is how I apply style to control:
switchControl->Style = makeSwitchControlStyle();
And that function simply uses xaml reader to load the xaml string below:
<Style x:Key="{x:Type ToggleSwitch}" TargetType="ToggleSwitch">
<Setter Property="Foreground" Value="{ThemeResource ToggleSwitchForegroundThemeBrush}"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
<Setter Property="FontWeight" Value="SemiBold"/>
<Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
<Setter Property="MinWidth" Value="154"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleSwitch">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Width="52" Height="23">

Now, this is a cut template of the original ToggleSwitch without extraneous labels and it looks like this:
I would like to expose method which wraps this class that could set, for instance, the color of a knob to blue/red etc. and similar things for other components of the original toggleswitch.
So, how do I set specific properties for control after I've loaded the style from hardcoded xaml string? How do I refer to properties from the style?
