XAML

Revision as of 13:51, 31 January 2018 by BMA (Talk | contribs) (→‎Basic)

The WinX User Interface can be vastly customized using XAML.

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 For further information see UBIK Templates.

General

Controls the overall styling and behavior of the App, like standard Brushes (Colors) and Fonts.

Converters

Basic

  • AddStringSuffixConverter

Appends a suffix expression to an existing (string) value. The suffix expression to be appended is provided via the converter parameter.

  • TypeToVisibilityConverter

Converts the presence of a type to visbility (e.g. whether an object is "String")

  • ValueValidityToVisibilityConverter


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>


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>


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>


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="ChildItemTemplateSelector" />
            <tpl:ChildItemTemplateSmallSelector x:Key="ChildItemTemplateSmallSelector" />
            <converters:ChildItemTemplateSelectorSuffixConverter x:Key="ChildItemTemplateSelectorSuffixConv" TemplateSelector="{Binding Source={StaticResource ChildItemTemplateSelector}}" TemplateSmallSelector="{Binding Source={StaticResource ChildItemTemplateSmallSelector}}"/>
        </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" -->

        <StackPanel>
            <CheckBox Grid.Column="0">
                <Interactivity:Interaction.Behaviors>
                    <Core:EventTriggerBehavior EventName="Checked">
                        <!-- Store the Profile Variable "ChildItemsViewMode" to Grid or List - depending on the check state of the check box -->
                        <Core:InvokeCommandAction Command="{Binding StoreProfileParameterCommand}" CommandParameter="ChildItemsViewMode=_Grid"/>
                    </Core:EventTriggerBehavior>
                    <Core:EventTriggerBehavior EventName="Unchecked">
                        <Core:InvokeCommandAction Command="{Binding StoreProfileParameterCommand}" CommandParameter="ChildItemsViewMode=_List"/>
                    </Core:EventTriggerBehavior>
                </Interactivity:Interaction.Behaviors>
            </CheckBox>
            <ListView
                   x:Name="ChildListView"
                   HorizontalContentAlignment="Stretch"
                   ItemTemplateSelector="{Binding Path=StoredProfileParameters[ChildItemsViewMode], Converter={StaticResource ChildItemTemplateSelectorSuffixConv}, ConverterParameter=Normal, FallbackValue=List}"
                   ItemsPanel="{StaticResource ChildPageItemsPanelTemplate}"
                   ItemsSource="{Binding Children.Items}"
                   ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionMode="None">
                <ListView.ItemContainerStyle>
                    <Style TargetType="ListViewItem">
                        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                        <Setter Property="Padding" Value="0" />
                        <Setter Property="Margin" Value="0,0,16,0" />
                    </Style>
                </ListView.ItemContainerStyle>
                <ListView.ItemContainerTransitions>
                    <TransitionCollection>
                        <EntranceThemeTransition FromHorizontalOffset="400" />
                    </TransitionCollection>
                </ListView.ItemContainerTransitions>
            </ListView>
        </StackPanel>
    </Grid>

Namespace changes

Starting from the UBIK UWP client, we have restructured & renamed some of our outdated or inaccurate namespaces. This means modifications are necessary for any previous XAML customizing code that refers to these changed namespaces. The complete list of such changes is documented below.

V.2.6 V.3.0
Name-
space
prefix 		UBIK.Win8 UBIK.WinX
UBIK.WinX.UI UBIK.UI
UBIK.WinX.Utility UBIK.Utility
UBIK.WinX.Library UBIK.Library
UBIK.WinX.DataProvider UBIK.DataProvider
UBIK.WinX.SyncHandler UBIK.SyncHandler
UBIK.WinX.DatabaseConnector UBIK.DatabaseConnector
UBIK.WinX.ContentDatabase UBIK.ContentDatabase
UBIK.WinX.MRO UBIK.MRO
UBIK.WinX.Coding UBIK.Coding
UBIK.WinX.DataService UBIK.DataService
UBIK.WinX.Redlining UBIK.Redlining
UBIK.WinX.Positioning UBIK.Positioning

Take the namespace UBIK.Win8 for example, it is now changed to UBIK.WinX. A few affected XAML namespace references are e.g.

  • using:UBIK.Win8.Views -> using:UBIK.WinX.Views
  • using:UBIK.Win8.GART.Controls -> using:UBIK.WinX.GART.Controls

Important notes on the namespace UBIK.WinX.UI:

  • One exception is the namespace UBIK.WinX.UI.CollectionView. It is not changed since the content is indeed WinX specific.
  • For namespaces that are changed from UBIK.Win8.UI such as UBIK.Win8.UI.Controls, do not further remove the WinX segment even though the results are something like UBIK.WinX.UI.Controls.
