How to change the properties of NavigaitonViewItems

Question

MainPage.xaml

 <NavigationView x:Name="NPPngv" x:FieldModifier="public">
       <NavigationView.MenuItems>
          <NavigationViewItem Content="Customer"/>
          <NavigationViewItem Content="Deliverer"/>
          <NavigationViewItem Content="Admin"/>
       </NavigationView.MenuItems>
       <Frame x:Name="contentFrame"/>
  </NavigationView>

Is there a way to change a property for each of the NavigationViewItems For example I want set all the items to IsEnabled=false but I need it to be repeatable and with any number of items.

Is it possible to create an array of the items and then iterate though it?

Answer 1

The MenuItems property returns an IList<object> so you could do this in the constructor of your Page:

public MainPage()
{
    this.InitializeComponent();

    foreach (var item in NPPngv.MenuItems.OfType<NavigationViewItem>())
    {
        item.IsEnabled = false;
    }
}

Don't forget to add using System.Linq; at the top of your source code file.
