Force Cancellation of ContentDialog

[mysteryx93]

As I'm working on mobile back button navigation, I've come onto a problem: cancelling a ContentDialog from "outside".

The dialog is shown here.

public Task<ContentDialogResult> ShowContentDialog(ContentControl? owner, ContentDialogSettings settings)
{
    var dialog = new ContentDialog()
    {
        Title = settings.Title,
        Content = settings.Content,
        CloseButtonText = settings.CloseButtonText,
        PrimaryButtonText = settings.PrimaryButtonText,
        SecondaryButtonText = settings.SecondaryButtonText,
        DefaultButton = settings.DefaultButton,
        IsPrimaryButtonEnabled = settings.IsPrimaryButtonEnabled,
        IsSecondaryButtonEnabled = settings.IsSecondaryButtonEnabled,
        FullSizeDesired = settings.FullSizeDesired
    };
    return dialog.ShowAsync();
}

Meanwhile, elsewhere in the application, I have this

public void TopLevel_BackRequested()
{
    // What now?
}

How can I close the ContentDialog from there?

ContentDialog has a Hide() method. Get a reference to the dialog, and call that.
