Unsaved changes on the document (e.g. Annotations) are gonna be saved and committed automatically when flipping the page in the FlipView.
{{Attention|Changes are lost when leaving the page without flipping the document first.}}
{{Version/WinXSince|4.7}} {{Version/XamarinSince|4.7}} If you want to keep the changes when leaving the page by e.g. navigating away without flipping the document first, there is a boolean property called ''AutoSaveDocumentsOnPageClose'' (default value: false) which enables this behavior. It can be activated by adding the property to the UBIKThemes.xaml as follows:
<tabs>
<tab name="UWP">
<source lang = "xml">
<x:String x:Key="AutoSaveDocumentsOnPageClose">true</x:String>
