How to customize CommandExtenions.CommandParameter for NavigationView

[kazo0]

is it possible and if yes, where would this be placed, if I would like to tell it to alyways provide the Invoked Items tag? with x:Bind I can get to the MenuItems but can not tell any future and on each Item its not doing anything, maybe only if I would have nested ones... Binding same just without the intellisense giving me choosable things. thought to ancestor or Itemscontrolbinding, but that would need a fixed type and as far as I understood it from the documentation this is only going upwards, not downwards in nested areas

Assuming you have access to the NVI under, in that case, you can set the CommandParameter on the NVI itself:

<NavigationView utu:CommandExtensions.Command="{Binding TestCommand}">
	<NavigationView.MenuItems>
		<NavigationViewItem Content="asd" Tag="a" utu:CommandExtensions.CommandParameter="a" />
		<NavigationViewItem Content="qwe" Tag="q" utu:CommandExtensions.CommandParameter="q" />
		<NavigationViewItem Content="zxc" Tag="z" utu:CommandExtensions.CommandParameter="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Tag}" />
	</NavigationView.MenuItems>
</NavigationView>
