I am developing a Window style without the default border, and currently I am trying to develop the custom Window buttons, placed in the top right corner, like the Close button.
The problem is that inserting a Path as content for a Button the focus is not rendered correctly when the mouse is on the Path inside.
Here a screenshot to explain the problem (I have added a "cursor" with paint because Windows remove it automatically)
This is the Button definition
<Button Grid.Row="0"
Grid.Column="1">

I've tried binding... but it seems that binding is not supported within a style?
Is there another way I can access those rects?
I am using ContentDialogs throughout my app on Windows 10 Mobile. Both ContentDialog and MessageDialog seem to prefer to anchor to the top of the screen by default. However, I have seen some apps where it shows right in the middle of the screen vertically so it appears as a strip. I cannot figure out how to position it in the middle vertically. I have tried this
cd.VerticalAlignment = VerticalAlignment.Center;
Where cd is my ContentDialog intance but this does not work. It is still anchored at the top of the window.
Thanks!
You should override Style for your ContentDialog. I've tried to setup VerticalAlignment.Center to Container, LayoutRoot and BackgroundElement but it doesn't help. So, place the BackgroundElement to center Row in LayoutRoot just added new RowDefinition and setup Grid.Row="1" for your BackgroundElement.
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
Look at the full ContentDialog Style.
NOTES
But be careful, because this works only for mobile. You should apply this style only for mobile platform.

I have a next style:
<Style x:Key="Style_MainButtons" TargetType="ToggleButton">
<Setter Property="Width" Value="110" />
<Setter Property="Height" Value="110" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />

<TextBlock x:Name="Text" HorizontalAlignment="Center" />
<Image x:Name="Image" Grid.Row="1" />
</Grid>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Because there are few toggle buttons using this style and each have different text and image, so how can I call “TextBlock” and “Image” from style in the next code?
<ToggleButton x:Name="btnHorizontal"
Style="{StaticResource Style_MainButtons}"
Grid.Column="0"
Grid.Row="1"
Checked ="SetVersion"
Unchecked ="SetVersion"
IsChecked="True" >
</ToggleButton>
You can do something like this:
Style
<Style TargetType="ToggleButton">
<Setter Property="Width" Value="110" />
<Setter Property="Height" Value="110" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock x:Name="Text" HorizontalAlignment="Center" Text="{TemplateBinding Content}"/>
<Image x:Name="Image" Grid.Row="1" Source="{TemplateBinding Tag}" />
</Grid>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Usage
<ToggleButton Content="Text" Tag="{Binding Path=Source, Source={StaticResource Image}}"></ToggleButton>
<ToggleButton Content="Another Text" Tag="{Binding Path=Source, Source={StaticResource Image}}"></ToggleButton>
Note: Replace my Tag-Binding with an valid Binding to your actual ImageSource
Is it possible to create some sort of base expander style and override the background color of the header in a derived style?
In my application I'm using expanders a lot and I would like to change the background color of the header. I know I could just copy&paste my style and edit the color, but it would be nicer to just create a new style based on the "base style" and setting the header's background color.
But I do not know how to access this color.
It's the color of this line: below I'd like to change (the border in the header): Border Name="border"... I cannot access "border" in the setter of the derived style...
This is my (base) style:

Because you are overriding the default template for the Window you are taking away the style effects (of which one is background = black on the root grid)
see above, i've put it in the template and it should now work (Background="White")
Below is the default template for a window (Taken From Blend)
<ControlTemplate x:Key="WindowTemplateKey" TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">

Based on TBohnen.jnr's answer, the actual correct answer would be do it as the default window template and add Background="{TemplateBinding Background}" to the top-level child element of the ControlTemplate. In the default template it is a Border, whereas in your case it's the Grid:
<Grid Background="{TemplateBinding Background}" Name="LayoutRoot" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
