Example

BitmapIconExtension

The BitmapIconExtension markup extension is similar in structure to the two previous extensions, but it produces BitmapIcon instances instead of font-based icons. Here is how it can be used:

1

<MenuFlyoutItem
        Text="No, click me!"
        Icon="{wuc:BitmapIcon Source=/Assets/myicon.png}" />

<MenuFlyoutItem
        Text="No, click me!"
        Icon="{wuc:BitmapIcon Source=/Assets/myicon.png, ShowAsMonochrome = true}" />

BitmapIconSourceExtension

The BitmapIconSourceExtension class mirrors the BitmapIconExtension type, with the only difference being that it returns a BitmapIconSource instance. Here is how it can be used:

<SwipeItems Mode="Reveal">
    <SwipeItem Text="Send" IconSource="{wuc:BitmapIconSource Source=/Assets/myicon.png}"/>
</SwipeItems>

FontIconExtension

The FontIconExtension type provides the ability to create FontIcon instances from XAML with a more compact representation than by explicitly creating a new FontIcon object to assign to the target property. The property also maps all the available FontIcon properties, so the two APIs expose the same set of customization options, just through a different XAML syntax:

Available Property	Remark
Glyph	Example: &#xE102
GlyphName	Choose Glyph by its name.
GlyphCode	Choose Glyph by its Code.

<CommandBar>
    <AppBarButton Icon="{wuc:FontIcon Glyph=&#xE102;}"/>
</CommandBar>

<CommandBar>
    <AppBarButton Icon="{wuc:FontIcon GlyphName=Accept}"/>
</CommandBar>

<CommandBar>
    <AppBarButton Icon="{wuc:FontIcon GlyphCode=E700}"/>
</CommandBar>

FontIconSourceExtension

The FontIconSourceExtension class mirrors the FontIconExtension type, but producing FontIconSource instances instead of FontIcon:

1
2
3

<SwipeItems Mode="Reveal">
    <SwipeItem Text="Accept" IconSource="{wuc:FontIconSource Glyph=&#xE10B;}"/>
</SwipeItems>

SymbolIconExtension

The SymbolIconExtension type mirrors the FontIcon markup extension, with the main difference being that it uses a Symbol value to specify the icon. All the other properties from FontIconExtension are available, with the exception of the font family. Here is how it can be used:

1
2
3

<CommandBar>
    <AppBarButton Icon="{wuc:SymbolIcon Symbol=Play}"/>
</CommandBar>

SymbolIconSource

The SymbolIconSourceExtension type is an alternative for FontIconSourceExtension that takes a Symbol value instead of a text, and displays the icon. It’s equivalent to the SymbolIconExtension type, except for the fact that it returns a FontIconSource instance:

1

3

<SwipeItems Mode="Reveal">
    <SwipeItem Text="Play" IconSource="{wuc:SymbolIconSource Symbol=Play}"/>
</SwipeItems>
