Examples

The following code example creates and initializes a DomainUpDown control. The example allows you to set some of its properties and create a collection of strings for display in the spin box (also known as an up-down control). The code assumes that a TextBox, CheckBox, and Button have been instantiated on a form. The example also assumes that you have a member variable at the class level declared as a 32-bit signed integer named myCounter. You can enter a string in the text box and add it to the Items collection when the button is clicked. By clicking the check box, you can toggle the Sorted property and observe the difference in the collection of items in the spin box.

Remarks

When Sorted is set to true, the collection is sorted in alphabetical order.
