Creating custom controls

Just like any other development platform, it is also possible to create custom views/controls that look, behave, and render differently compared to the out-of-the-box Xamarin.Forms controls; however, creating a custom control doesn't mean that the complete Xamarin.Forms render infrastructure needs to be implemented for target platforms as well as the shared domain. Depending on the UX and platform requirements, the following can occur:

• Custom controls can be created solely as a composition of other Xamarin.Forms controls
• Existing Xamarin.Forms controls can be modified with custom renderers on different platforms
• Custom Xamarin.Forms controls can be created with custom renderers
