This can be useful if your app has a lot of text since the initial loading time for such an app's text elements can be too high to do without a noticable delay.

If this property is set to true, the WhileLoading trigger is active while the text is loading.

Example

The following code displays a green background while a piece of text is loading on the background thread, and fades in the text when it's available.

<Panel ux:Name="_loading" Background="#0F0" Opacity="0.0"/>
<Text ux:Name="_text" Value="Some text" LoadAsync="true" >
    <WhileLoading>
        <Change _loading.Opacity="1.0" Duration="0.5" />
        <Change _text.Opacity="0.0"  Duration="0.5" />
    </WhileLoading>
</Text>

Remarks

This property currently only works when running on an actual device and using the Harbuzz text renderer (enabled on desktop or by building for device with -DUSE_HARFBUZZ).
