Ok I’ve knocked up a simple example to show you how you can dynamically change the content of the ContentControl using a MVVM(Model-View-ViewModel) approach with data binding. I would recommend that you create a new project and load these files to see how it all works. We first need to implement INotifyPropertyChanged interface. This will … Read more
Creating template in codebehind is not a good idea, in theory one would do this by defining the ControlTemplate.VisualTree which is a FrameworkElementFactory. ControlTemplate template = new ControlTemplate(typeof(Button)); var image = new FrameworkElementFactory(typeof(Image)); template.VisualTree = image; Assigning properties is very roundabout since you need to use SetValue and SetBinding: image.SetValue(Image.SourceProperty, …); Also, about the (previously) … Read more

Interesting point from MSDN: If a Control does not have a ControlTemplate, the Control will not appear in your application.
