Setting the ControlTemplate programmatically is just like using XAML because we have to use the XamlReader class. For example, here is the code to set a button's template, assuming that we want to set a button's template after it is loaded.

private void Button_Loaded(object sender, RoutedEventArgs e) {
    var button = sender as Button;
    string template =
        "" +
            "" +
                 "" +
            "" +
        "";
    button.Template = (ControlTemplate)XamlReader.Parse(template);
}

Since we used a string for specifying the XAML code for the template, we can use the XamlReader's Parse method. The XamlReader also has a Load method, which is primarily used for streams or XAML or XML readers. Notice that we have to include the XML namespace http://schemas.microsoft.com/winfx/2006/xaml/presentation because the ControlTemplate, Border, and other controls we need are defined there. If we did not include it, we'll encounter a runtime exception. Basically, we have to put the namespaces needed by the template.
