Dynamically adding/removing elements in a panel

So far, we have seen how to add static elements/contents in a Panel control. But it's not always useful, mainly when you are retrieving data from the backend and populating in the UI or dynamically based on the user interaction.

This recipe will discuss this topic. As all the panels perform similarly to add/remove elements, with a slight difference on the positioning, we will be demonstrating it with a simple Canvas.
