Page Anchors

Last updated 22 days ago

Overview

Page Anchors allow navigation directly to specific elements on a new page during page navigation. This feature enhances user experience by allowing deep linking into a specific part of a new page immediately upon navigation.

Example

<Button Text="Anchor scroll"
        Command="{Binding PushPage}"
        StyleClass="btn, btn-primary" 
        CommandParameter="5f4ef280-d58f-4c32-904d-49ef5e9904d7?PersonId=1#test" />

This example includes:

  • A page GUID: 5f4ef280-d58f-4c32-904d-49ef5e9904d7

  • A query parameter: PersonId=1

  • An anchor fragment: #test

Upon navigation, the page will automatically scroll to the element named test.


Defining Anchor Targets

To define a scrollable target on your page, set the x:Name attribute on the element you want to anchor to.

Example:

<ScrollView>
    <StackLayout>
        <ContentView Grid.Row="0" BackgroundColor="Red" HeightRequest="200"/>
        <ContentView Grid.Row="1" BackgroundColor="Green" HeightRequest="200"/>
        <ContentView Grid.Row="2" BackgroundColor="Blue" HeightRequest="200"/>
        <ContentView x:Name="test" Grid.Row="3" BackgroundColor="Black" HeightRequest="200"/>
        <ContentView Grid.Row="4" BackgroundColor="Purple" HeightRequest="200"/>
        <ContentView Grid.Row="5" BackgroundColor="White" HeightRequest="200"/>
        <ContentView Grid.Row="6" BackgroundColor="Orange" HeightRequest="200"/>
        <ContentView Grid.Row="7" BackgroundColor="Yellow" HeightRequest="200"/>
    </StackLayout>
</ScrollView>

In this example, the element named test will be the target for the anchor scroll.


Advanced Example

You can specify anchor scrolling options using PushPageParameters and AnchorScrollParameters.

<Button Text="Anchor Scroll Options"
        Command="{Binding PushPage}"
        StyleClass="btn, btn-primary">
        <Button.CommandParameter>
            <Rock:PushPageParameters PageGuid="5f4ef280-d58f-4c32-904d-49ef5e9904d7" >
                 <Rock:PushPageParameters.AnchorOptions>
                    <Rock:AnchorScrollParameters AnchorId="test" Position="Center" />
                </Rock:PushPageParameters.AnchorOptions>
                <Rock:Parameter Name="PersonId" Value="562sWgf" />
            </Rock:PushPageParameters>
        </Button.CommandParameter>
    </Button>
