DomainUpDown. How can you present a limited selection of options? This should use only minimal screen space. In Windows Forms, you can provide a DomainUpDown control.
Up, down arrows. The DomainUpDown control has nothing to do with website domain names. Instead, it has an up and down arrow box that selects the current text item.
Example. A good place to initialize the DomainUpDown control is in the Load event of the enclosing form. Please double-click on the enclosing form to create this event.
Form
Next We add several items to the DomainUpDown control. The current item can be determined or set with the Text property.
using System; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { // Items. DomainUpDown.DomainUpDownItemCollection items = this.domainUpDown1.Items; items.Add("Dot"); items.Add("Net"); items.Add("Perls"); // Set Text. this.domainUpDown1.Text = "Dot"; } private void domainUpDown1_SelectedItemChanged(object sender, EventArgs e) { // Run code every time the item is changed. this.Text = domainUpDown1.Text; } } }
SelectedItemChanged. Every time the selected item is changed by the user, this code is executed. We set the Text property of the Form to the current item in the DomainUpDown.

Property
A summary. The DomainUpDown control provides an alternative to radio buttons or other pull-down lists. It can be useful in a variety of places, including preferences dialogs.
