WPF. How to properly bind multiple ListView located in TabControl to one property?

Question

Android

The page has a TabControl with two tabs, each tab has one ListView. The ItemsSource properties of the ListView items are associated with a single ItemsSource specified in the page resources. When you first view the tabs, both ListViews are filled, i.e. the binding worked, but when re-viewing, only one ListView remains filled, the second one turns out to be empty. Help me to understand! Simplified, it looks like this:

------
<Page.Resources>
 <ItemsSource x:Name="ISource" x:Key="ISource"/>  
</Page.Resources>  

--------

<TabControl>
  <TabItem>
<ListView ItemsSource = "{Binding ItemsSource, ElementName ISource}" />
</TabItem>
   <TabItem>
<ListView ItemsSource = "{Binding ItemsSource, ElementName ISource}" />
</TabItem>
</TabControl>

Answer 1

The Resources section declares the control's static resources. They need to be used like this:
x:Name is not needed in this case, only x:Key.
