Creating a User Control
In this section, we’ll create a simple user control called NumericUpDown, which provides a numeric display with associated increment and decrement buttons that enable the user to change its value.
First, we add a new user control to a Visual Studio solution by selecting User Control from the Add New Item dialog. If you do this and name it NumericUpDown, you get NumericUpDown.xaml and its NumericUpDown.xaml.cs code-behind file added to your project. This defines a NumericUpDown class that derives from UserControl, a simple control with a Content property of type UIElement. (Note that Content does not support generic objects, so UserControl is not a content control.)
