Documentation for this section has not yet been entered.
Remarks
Use the HtmlSelect.Multiple property to specify whether multiple items can be concurrently selected in the System.Web.UI.HtmlControls.HtmlSelect control.
By default, the System.Web.UI.HtmlControls.HtmlSelect control is displayed as a drop-down list box. If you allow multiple selections (by setting the HtmlSelect.Multiple property to true) or specify a height greater than one row (by setting the HtmlSelect.Size property to a value greater than 1), the control is displayed as a list box.
To determine the selected items in an System.Web.UI.HtmlControls.HtmlSelect control that allows multiple simultaneous selections, iterate through the HtmlSelect.Items collection and test the System.Web.UI.WebControls.ListItem.Selected property of each item.
The multiple attribute is rendered in the System.Web.UI.HtmlControls.HtmlSelect control only if this property is set to true.
