In the following example the TextInput’s Background changes when focused. However when I tap the down arrow (left button on the bottom menu) on the Android keyboard and the keyboard discards, the TextInput stays in focus. How can I lose focus of the TextInput when discarding the keyboard?
<App>
<TextInput ux:Name="TextInput" Width="100%" Height="50" Background="#0000ff">
<WhileFocused>
<Set TextInput.Background="#ff0000" />
</WhileFocused>
<WhileNotFocused>
<Set TextInput.Background="#0000ff" />
</WhileNotFocused>
</TextInput>
</App>
