How to handle conflicting Visual State Setters in separate Visual State Groups?

Let's say I've got a RadioButton style defined in a XAML ResourceDictionary (no code-behind):
<Style x:Key="ExampleRadioButtonStyle"
TargetType="RadioButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<Grid x:Name="Root">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="PointerOver">
<VisualState.Setters>
???
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<VisualState.Setters>
<Setter Target="Content.Fill" Value="White" />
<Setter Target="Content.Stroke" Value="Blue" />
</VisualState.Setters>
</VisualState>
<VisualState x:Name="Unchecked">
<VisualState.Setters>
<Setter Target="Content.Fill" Value="Transparent" />
<Setter Target="Content.Stroke" Value="Black" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Ellipse x:Name="Content"
StrokeThickness="5"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
Now I want to change the Content.Stroke property when the CommonStates.CurrentState is PointerOver to:
Cyan when the CheckStates.CurrentState is Checked
Gray when the CheckStates.CurrentState is Unchecked
What is the best way to achieve that?
Please note that this is just a simplified example prepared to present my problem which is much more complex in reality (for example I need to handle all CommonStates) so I look for a decent solution not a simple workaround handling only the mouse over behavior.

According to the code you provided, we can't directly get the selected state of the RadioButton from PointerOver.You can follow the native style,create two Ellipse,one for the selected state and the other for the unselected.Use the Check status switch to show or hideEllipse.Then set the stroke in PointerOver.For example:
<Ellipse x:Name="Content" Fill="{StaticResource RadioButtonOuterEllipseFill}" Height="20" StrokeThickness="{ThemeResource RadioButtonBorderThemeThickness}" Stroke="{ThemeResource RadioButtonOuterEllipseStroke}" UseLayoutRounding="False" Width="20"/>
<Ellipse x:Name="CheckedContent" Fill="{ThemeResource RadioButtonOuterEllipseCheckedFill}" Height="20" Opacity="0" StrokeThickness="{ThemeResource RadioButtonBorderThemeThickness}" Stroke="{ThemeResource RadioButtonOuterEllipseCheckedStroke}" UseLayoutRounding="False" Width="20"/>
When the CheckStates.CurrentState is Checked,you can show the CheckedContent and hide Content,the UnChecked the opposite.
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<VisualState.Setters>
<Setter Target="Content.Opacity" Value="0"></Setter>
<Setter Target="CheckedContent.Opacity" Value="1"></Setter>
<Setter Target="CheckedContent.Fill" Value="White" />
<Setter Target="CheckedContent.Stroke" Value="Blue" />
</VisualState.Setters>
</VisualState>
......
</VisualStateGroup>
Then you can set stroke for different states in PointerOver.
<VisualState x:Name="PointerOver">
<VisualState.Setters>​
<Setter Target="Content.Stroke" Value="Gray"></Setter>​
<Setter Target="CheckedContent.Stroke" Value="Cyan"></Setter>​
</VisualState.Setters>​
</VisualState>

UWP Hub need vertical scrolling

for testing purposes I have a Hub control in UWP that looks like this:
<Hub x:Name="hubTest1">
<HubSection Margin="10,0,0,0" Width="200" Background="CadetBlue" ScrollViewer.VerticalScrollMode="Enabled" HorizontalContentAlignment="Stretch" Header="#" VerticalAlignment="Stretch">
<HubSection.HeaderTemplate>
<DataTemplate>
<TextBlock Foreground="White">This is some Test</TextBlock>
</DataTemplate>
</HubSection.HeaderTemplate>
<DataTemplate>
<ScrollViewer HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" Margin="0,0,0,0">
<RichTextBlock Height="1000" Foreground="White" TextWrapping="Wrap" HorizontalAlignment="Stretch">
<Paragraph>
This is a test.
<LineBreak></LineBreak>
This is a test.
<LineBreak></LineBreak>
This is a test.
<LineBreak></LineBreak>
... Repeated many times ...
</Paragraph>
</RichTextBlock>
</ScrollViewer>
</DataTemplate>
</HubSection>
<HubSection Margin="10,0,0,0" Background="BlueViolet" Width="300" Foreground="White" HorizontalContentAlignment="Stretch" Header="#">
<HubSection.HeaderTemplate>
<DataTemplate>
<TextBlock Foreground="White">This is some Test</TextBlock>
</DataTemplate>
</HubSection.HeaderTemplate>
<DataTemplate>
<TextBlock>This is a test 2</TextBlock>
</DataTemplate>
</HubSection>
</Hub>
Where I'm having trouble is I want the first HubSection to be scrollable off the page vertically when filled with more content than the screen. It only goes to the edge though. The inside ScrollViewer does scroll the text down vertically, but it's inside the inner container of the DataTemplate and isn't giving the necessary result. Also the Hub is inside a SplitView.Content container, I'm not sure if that affects the behavior of the Hub or not. I'm wondering if it's possible to get the desired behavior? Any help you guys can give is greatly appreciated.

The inside ScrollViewer doesn't go all the way down because you gave the RichTextBlock a fixed Height of 1000px. Remove it and the problem should go away.
Also it's OK to put the Hub inside a SplitView and have vertically scrolling content too.
Update
If you want the whole HubSection including the header to be scrollable, two things you need to do:
Remove the ScrollViewer inside your DataTemplate.
Create a new Style for your HubSection and inside its
ControlTemplate, insert a new ScrollViewer as its top level
container. Something like this -
<Style x:Key="HubSectionStyle1"
TargetType="HubSection">
<Setter Property="HorizontalAlignment"
Value="Stretch" />
<Setter Property="VerticalAlignment"

Xamarin : Segmented Control for windows uwp

How can I make a custom renderer for Segmented Control in windows UWP. I followed this link to custom render the segmented control in IOS and android. But I couldn't find anything for windows UWP. Can anyone provide any resource in this or is there any alternate way of doing this similar to segmented control in windows UWP.

I found the Solution myself.
I recently found a nuget package FreshEssentials. It has the implementation of segmented button group. Follow this github link to find the implementation. It is easy to use.

There is a Xamarin Forms cross platform library now that does this.
Plugin Segmented Control for .NET Standard

I did it once with custom-styled RadioButtons. Edit the RadioButton style for your buttons - create checked and unchecked styles that are looking as you want and give them the same group so you can select only one button at the time.
Don't know if there is any easier way.
edit: sampe code, edit it the way you want:

Toggle Switch color Windows Phone 8

I'm creating an app where on my main page I have a list with a ToggleSwitch control on each row but the control doesn't appear on the phone emulator. The XAML for the ToggleSwitch control is as below:
<toolkit:ToggleSwitch x:Name="ToggleSwitch" IsChecked="false" Content="Content Goes here" Checked="switch_Unchecked" Unchecked="switch_Unchecked" BorderBrush="black" Background="Black" Width="200"/>
When I click on that code, it shows me that:
So I believe that the control with BorderBrush=black and Background=Black is at the right place but it doesn't appear...
May somebody helps me with that ?

What's the color of your Grid Background color? There might be some problem with that too. Try applying the following style for the Toggle Switch.
<Grid x:Name="LayoutRoot" Background="White">
<toolkit:ToggleSwitch Margin="12,0" Content="Live Update" Background="White" Foreground="Black" Style="{StaticResource FixedToggleSwitchStyle}"/>
</Grid>
And the style is,
<Style x:Key="FixedToggleSwitchButtonStyle" TargetType="toolkitPrimitives:ToggleSwitchButton">
<Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
<Setter Property="Background" Value="{StaticResource PhoneBackgroundBrush}"/>

Change your Background color and Foreground color as per your needs in Toggle Switch.

Have either one of these property, Background or the BorderBrush.
Why don't you try it this way?
xaml:
<ToggleSwitch x:Name="toggleSwitch1" Header="ToggleSwitch"
OnContent="On" OffContent="Off"
Toggled="ToggleSwitch_Toggled"/>
private void ToggleSwitch_Toggled(object sender, RoutedEventArgs e)
{
// Add code to perform some action here.
}
Have a look at this too. Is that the one you're using from the Toolkit or what?
Hope it helps!

Here i have added two colors one for default item color "#e3e8f0" and one is Selected item and MouseOver color "#c9ebf2" in my style
Now I have a button and its click event in my .CS file Now when i click on that the Selected item and MouseOver color "#c9ebf2" should be changed to Green color,
How to acheive this ?

You have given #c9ebf2 color for both mouseover and selected state in your style. Change your color for selected state.
