UWP - Prevent NavigationViewItemHeader from being clipped

Question

I am writing a UWP app that has a NavigationView containing NavigationViewItemHeaders:

   <NavigationView.MenuItems>
        <NavigationViewItem Content="Home" Tag="home">
            <NavigationViewItem.Icon>
                <FontIcon Glyph="&#xE80F;"/>
            </NavigationViewItem.Icon>
        </NavigationViewItem>

        <NavigationViewItemSeparator/>
        <NavigationViewItemHeader x:Name="ThemesHeading" Content="Themes"/>

        <NavigationViewItem Content="Themes" Tag="themes">
            <NavigationViewItem.Icon>
                <FontIcon Glyph="&#xE771;"/>
            </NavigationViewItem.Icon>
        </NavigationViewItem>

(and so on)

However when I collapse the view, the headers get clipped:

What should I do to prevent this?

Answer 1

Solution 1

Increase the left margin of item headers:

<NavigationViewItemHeader Content="Themes" Margin="33,0,0,0"/>
...
<NavigationViewItemHeader Content="Builds" Margin="33,0,0,0"/>

Solution 2

Disable compact and expanded display mode of the NavigationView by setting the CompactModeThresholdWidth and ExpandedModeThresholdWidth to some big number:

<NavigationView CompactModeThresholdWidth="100000" ExpandedModeThresholdWidth="100000">

Solution 3

Bind the Visibility property of item headers to the IsPaneOpen property of the NavigationView as André B suggested, only use x:Bind instead of Binding since it doesn't need a converter:

<NavigationView Name="MyNavigationView">
    ...
            <NavigationViewItemHeader Content="Themes" Visibility="{x:Bind MyNavigationView.IsPaneOpen, Mode=OneWay}"/>
    ...
            <NavigationViewItemHeader Content="Builds" Visibility="{x:Bind MyNavigationView.IsPaneOpen, Mode=OneWay}"/>
    ...
</NavigationView>
