Programmatically add Content to the Popup control in Silverlight

Adding a Popup to a Silverlight application is as easy as dragging and dropping a Popup control from the ToolBox

<Popup x:Name="popup" />

However if you want to programmatically add content to the Popup control, here’s how to do so:

private void Button_Click(object sender, RoutedEventArgs e)
{       
    //Create Popup content with a border, background color
    // and a child element Button
    popup.Child = new Border()
    {
        Height= 150,
        Width=150,
        Background = new SolidColorBrush(Colors.LightGray),
        Child = new Button() { Content = "OK", Height=50, Width=50 }
    };

    // Show/hide Popup
    popup.IsOpen = !popup.IsOpen;
}
}

As you can see, we are programmatically adding a Border element, specifying attributes of the Popup like Height, Width, Background Color and also adding a Button inside the popup, with attributes of its own. It’s common for developers to use the Popup type to create Cascading Menus programmatically!
