Questions tagged [wpf-controls]

WPF controls include UserControls, which are composite collections of other controls, and CustomControls, which are controls built with WPF styles and templates.

From Microsoft documentation:
Windows Presentation Foundation (WPF) ships with many of the common UI components that are used in almost every Windows application, such as Button, Label, TextBox, Menu, and ListBox. Historically, these objects have been referred to as controls. While the WPF SDK continues to use the term "control" to loosely mean any class that represents a visible object in an application, it is important to note that a class does not need to inherit from the Control class to have a visible presence. Classes that inherit from the Control class (AKA "Custom Controls") contain a ControlTemplate, which allows the consumer of a control to radically change the control's appearance without having to create a new subclass.
