ASP.NET in a Nutshell

Name

HtmlSelect

Synopsis

This class represents the HTML <select> tag, which allows the user to choose an option from a drop-down list box. To add an item to the list, use the Add() method of the Items property. The HtmlSelect control also supports data binding to its Items property.

To retrieve the currently selected item, you can use SelectedIndex property to find the ordinal number of the chosen item (-1 if no selection has been made), or the Value property to retrieve the text of the selected item. If you have set Multiple to True, more than one item may be selected and only the first item will be returned by the SelectedIndex and Value properties. Instead, you will have to iterate through the Items collection and check the System.Web.UI.WebControls.ListItem.Selected property for each one.

You can also react to the ServerChange event, which will fire only after a postback is triggered (for example, when the user clicks a submit button).
