HtmlSelect::Multiple Property
Gets or sets a value indicating whether multiple items can be selected concurrently in the HtmlSelect control.
Assembly: System.Web (in System.Web.dll)
<asp:HtmlSelect Multiple="True|False" />
Property Value
Type: System::Booleantrue if multiple items can be concurrently selected in the HtmlSelect control; otherwise, false. The default value is false.
Use the Multiple property to specify whether multiple items can be concurrently selected in the HtmlSelect control.
By default, the HtmlSelect control is displayed as a drop-down list box. If you allow multiple selections (by setting the Multiple property to true) or specify a height greater than one row (by setting the Size property to a value greater than 1), the control is displayed as a list box.
To determine the selected items in an HtmlSelect control that allows multiple simultaneous selections, iterate through the Items collection and test the ListItem::Selected property of each item.

The multiple attribute is rendered in the HtmlSelect control only if this property is set to true. |
