User Control

A user control is a reusable collection of controls which, after creation, is available in the toolbox like a standard control. The context menu option Add new Item… can be used to create a user control within the project tree.

	When a User Control is added, a User Control Host is created that points to the User Control. Therefore, every change to an attribute (for example the background color) acts from the outside on the user control host and from the inside on the user control.
