c# - WPF: Selectable usercontrol - How? -

I'm new to C # and WPF and there is a problem I hope you can help with it.

I have a WPF application with a stackpanel for which I add the user control by code to display the information stored in a class example. User can create an example, and selecting usercontrol is necessary to edit and delete class instances. In the example, to create a simple sketch as part of the information stored, there is a canvas in the user control.

My problem is how can I select user controls, so that users can choose or delete an instance for editing, and so that I can address canvas by code in a particular example Am I

I hope you can help me.
