The WinX User Interface can be vastly customized using XAML.
Contents
Templates
The UI is controlled by several predefined XAML templates which are loaded into the App at startup. There is a set of default template deployed with the App at installation, however, each of them can be overridden by placing the respective file in the folder [AppInstallPath]\LocalState\XAML
General
- UBIKThemes.xaml
Controls the overall styling and behavior of the App, like standard Brushes (Colors) and Fonts.
AuthenticationPage
- UBIKSplashArea.xaml
- UBIKPageNavigation.xaml
Content Pages
- UBIKObjectIcon.xaml
- UBIKObjectIconSmall.xaml
RootPage
- UBIKMainLeftArea.xaml
- UBIKMainItem.xaml
- UBIKMainItemSmall.xaml
ChildPage
- UBIKChildItem.xaml
- UBIKChildItemSmall.xaml
- UBIKChildAction.xaml
- UBIKPriorityPropertyItem.xaml

Converters
Basic
- BooleanToVisibilityConverter
Converts a Boolean into a Visibility, where true will result in Visibility.Visible.
- BooleanToCollapsedConverter
Converts a Boolean into a Visibility, where true will result in Visibility.Collapsed.
Advanced
Returns a formatted string where placeholders will be filled with values supplied to its parameter properties (Param0, Param1, Param2).
Example:
<StackPanel Orientation="Horizontal">
<StackPanel.Resources>
<!-- Instantiate the converter and bind the the Param0 to a SearchBox on this page -->
<converters:StringFormatConverter x:Key="URIConverter" Param0="{Binding ElementName=SkypeQuery, Path=QueryText}" />
</StackPanel.Resources>
<!-- Create a SearchBox that calls the typed Name via Skype on enter -->
<SearchBox
x:Name="SkypeQuery"
Width="240" Height="40"
FontSize="18"
PlaceholderText="Call Skype">
<Interactivity:Interaction.Behaviors>
<Core:EventTriggerBehavior EventName="QuerySubmitted">
<Core:InvokeCommandAction
Command="{Binding NavigateToURICommand}"
CommandParameter="{Binding ElementName=SkypeQuery, Path=QueryText, Converter={StaticResource URIConverter},
ConverterParameter=skype\:\{0\}\?call }" />
</Core:EventTriggerBehavior>
</Interactivity:Interaction.Behaviors>
</SearchBox>
</StackPanel>
<StackPanel.Resources>
<!-- Instantiate the converter and bind the the Param0 to a SearchBox on this page -->
<converters:StringFormatConverter x:Key="URIConverter" Param0="{Binding ElementName=SkypeQuery, Path=QueryText}" />
</StackPanel.Resources>
<!-- Create a SearchBox that calls the typed Name via Skype on enter -->
<SearchBox
x:Name="SkypeQuery"
Width="240" Height="40"
FontSize="18"
PlaceholderText="Call Skype">
<Interactivity:Interaction.Behaviors>
<Core:EventTriggerBehavior EventName="QuerySubmitted">
<Core:InvokeCommandAction

CommandParameter="{Binding ElementName=SkypeQuery, Path=QueryText, Converter={StaticResource URIConverter},

</Core:EventTriggerBehavior>
</Interactivity:Interaction.Behaviors>
</SearchBox>
</StackPanel>
Evaluates a C# expression with 3 optional variables (Param0, Param1, Param2) and returns the result. The object fed into the converter can be referenced in the expression as Context.
Example:
<Grid>
<Grid.Resources>
<!-- Instantiate the converter and bind the Context to the current DataContext, the Param0 to a UI element of this page -->
<converters:EvalExpressionConverter x:Key="CodeConverter" Context="{Binding}" Param0="{Binding ElementName=ChildListView, Path=Name}" />
</Grid.Resources>
<StackPanel Orientation="Horizontal">
<!-- Create a TextBox where we can enter a C# expression -->
<TextBox
x:Name="CodeQuery"
MinWidth="240" Height="40"
FontSize="18"
PlaceholderText="Expression">
</TextBox>
<!-- Create a TextBlock where we display the result of the compiled expression -->
<TextBlock Text="{Binding ElementName=CodeQuery, Path=Text, Converter={StaticResource CodeConverter}}" />
</StackPanel>
</Grid>
<Grid.Resources>
<!-- Instantiate the converter and bind the Context to the current DataContext, the Param0 to a UI element of this page -->
<converters:EvalExpressionConverter x:Key="CodeConverter" Context="{Binding}" Param0="{Binding ElementName=ChildListView, Path=Name}" />
</Grid.Resources>
<StackPanel Orientation="Horizontal">
<!-- Create a TextBox where we can enter a C# expression -->
<TextBox
x:Name="CodeQuery"
MinWidth="240" Height="40"
FontSize="18"
PlaceholderText="Expression">
</TextBox>
<!-- Create a TextBlock where we display the result of the compiled expression -->
<TextBlock Text="{Binding ElementName=CodeQuery, Path=Text, Converter={StaticResource CodeConverter}}" />
</StackPanel>
</Grid>
Converts a collection into a view that can be filtered using C# expressions and returns the (filtered) result. The object fed into the converter can be referenced in the expression as Item.
Example:
<Grid>
<Grid.Resources>
<!-- Instantiate the converter and bind the Source to the collection we want to use on a UI element of this page -->
<converters:CollectionToViewConverter x:Key="ColConv" Source="{Binding Children.Items}" />
</Grid.Resources>
<StackPanel Orientation="Horizontal">
<!-- Create a TextBox where we can enter a C# expression -->
<TextBox
x:Name="FilterQuery"
Height="40" MinWidth="240"
Margin="0,10,10,0" HorizontalAlignment="Right"
VerticalAlignment="Top"
FontSize="18"
PlaceholderText="Filter" />
<!-- Create a ListView and bind its ItemsSource to the expression pulled through the converter -->
<ListView
x:Name="ChildListView"
HorizontalContentAlignment="Stretch"
ItemsSource="{Binding ElementName=FilterQuery, Path=Text, Converter={StaticResource ColConv}}">
</ListView>
</StackPanel>
</Grid>
<Grid.Resources>
<!-- Instantiate the converter and bind the Source to the collection we want to use on a UI element of this page -->
<converters:CollectionToViewConverter x:Key="ColConv" Source="{Binding Children.Items}" />
</Grid.Resources>
<StackPanel Orientation="Horizontal">
<!-- Create a TextBox where we can enter a C# expression -->
<TextBox
x:Name="FilterQuery"
Height="40" MinWidth="240"
Margin="0,10,10,0" HorizontalAlignment="Right"
VerticalAlignment="Top"
FontSize="18"
PlaceholderText="Filter" />
<!-- Create a ListView and bind its ItemsSource to the expression pulled through the converter -->
<ListView
x:Name="ChildListView"
HorizontalContentAlignment="Stretch"
ItemsSource="{Binding ElementName=FilterQuery, Path=Text, Converter={StaticResource ColConv}}">
</ListView>
</StackPanel>
</Grid>
Converts a template selector to use templates with a certain suffix (e.g. "_Grid" to use "UBIKChildItem_Grid.xaml" instead of "UBIKChildItem.xaml"). The small template file name will be combined as <TemplateName><Suffix>Small.xaml (e.g. "UBIKChildItem_GridSmall.xaml").
Example:
<Grid>
<Grid.Resources>
<!-- Instantiate the template selectors and bind them to the instance of the coverter -->
<tpl:ChildItemTemplateSelector x:Key="ChildTemplateSelector" />
<tpl:ChildTemplateSmallSelector x:Key="ChildTemplateSmallSelector" />
<converters:ChildTemplateSelectorSuffixConverter x:Key="ChildTemplateSelectorSuffixConv" TemplateSelector="{Binding Source={StaticResource ChildTemplateSelector}}" TemplateSmallSelector="{Binding Source={StaticResource ChildTemplateSmallSelector}}"/>
</Grid.Resources>
<!-- The itemselector template binds to the suffix that should be used (in this case a binding to a stored profile parameter is used to switch the item template suffix between "_Grid" and "_List" -->
