How to go back to HomePage by using base page that contains SplitView

Question

I'm having a problem related to handle events. I had MainPage which contained a SplitView. It might be a base page. There were 2 buttons used to navigate frame in SplitView.Contant. A button is used to navigate to HomePage. The other is used to navigate to a page that contains a form to fill some fields. the page's name is AddSomething. I want to back to my home page immediately after clicking on button "Save".

MainPage XAML:

<SplitView x:Name="MainMenu" DisplayMode="Overlay">
    <SplitView.Pane>
        <Grid>
            <StackPanel>
                <Button x:Name="BtHome"
                        HorizontalAlignment="Stretch"
                        Content="Home"/>
                <Button x:Name="BtAddSth"
                        HorizontalAlignment="Stretch"
                        Content="Add Something"/>
            </StackPanel>
        </Grid>
    </SplitView.Pane>
    <SplitView.Content>
        <Frame x:Name="NavigatedFrame"/> <-! That's used to navigate -->
    </SplitView.Content>
</SplitView>`

AddSomthingPage XAML:

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <StackPanel VerticalAlignment="Center">
        <TextBox x:Name="Name" PlaceholderText="Name"/>
        <TextBox x:Name="Place" PlaceholderText="Place"/>

        <Grid HorizontalAlignment="Center">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Button x:Name="BtSaveToDB"
                    Grid.Column="0"
                    Content="Save"/>
            <Button x:Name="BtReset"
                    Grid.Column="1"
                    Content="Reset"/>
        </Grid>
    </StackPanel>
</Grid>

When I click on button "Save", I can go back to the home page. I don't want any change in my xaml. Especially I don't want to load MainPage anymore. Thanks in advance.

Answer 1

When you click save

// this will tell NavigatedFrame to go 
// back to previous page, assume that you set it to navigate to MainPage first
NavigatedFrame.GoBack()

In MainPage.xaml, add this line to thet Page node

NavigationCacheMode="Required"

It will cache the mainpage and prevent it from loading again.
