Add Children to element of type Page created in code behind Windows Phone 8.1

I can create a new element of type Page in code behind, but I want to add children elements of type UIElement as I would to a Grid like: myGrid.Children.Add(myUIElement);
I don't have the Children property and setting the Content property does not work.
How can I achieve this?

UPDATE:
This is what I have so far, but does not work:

Page myNewPage = new Page();
Grid myGrid = new Grid();
TextBlock myText = new TextBlock();
myText.Text = "I am a TextBlock!";
myGrid.Children.Add(myText);
myNewPage.Content = myGrid;

Frame.Navigate(myNewPage.GetType());

A Page can host a single UIElement in its Content property. To add several children, you have to do it like you would do it in XAML: add a panel that can contain and layout several children and add your elements to that panel.

In your question you talk about a grid called myGrid. You could add and layout your items in myGrid and then set myGrid as yourPage.Content.

Your code correctly builds the page. The problem with your code is that your Frame is navigating to a new instance of Page that is not the one that you created. Frame creates a new instance of the type that you pass as a parameter.

If you want to create a page fully in code, you can simply create class that extends Page and build the page in its constructor:

public class MyPage : Page
{
    public MyPage()
    {
        this.BuildPage();
    }

    private void BuildPage()
    {
        var panel = new StackPanel();
        panel.Children.Add(new TextBlock { Text = "Hello" });
        panel.Children.Add(new TextBlock { Text = "World" });

        this.Content = panel;
    }
}

That's, after all, what the InitializeComponent method does in pages created in XAML.
