WPF: can save a UserControl as XAML or BAML at run tiime?

[Haiping]

I have a UserControl whith Canvas as its content. It lets uses add controls,
Labels, TextBox, Charts, into this UserControl. After user is done with it
can it be saved as XAML or BAML file? So later user can load his file, and
edit it. If the UserControl cannot be saved as XAML or BAML what is the
other way to save it ?

thanks for any inputs,

to a xaml file. You can use XamlReader to convert a xaml string to a
UserControl.
