HtmlSelect::Multiple Property

Gets or sets a value indicating whether multiple items can be selected concurrently in the HtmlSelect control.

Namespace:  System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public:
property bool Multiple {
	bool get ();
	void set (bool value);
}
<asp:HtmlSelect Multiple="True|False" />

Property Value

Type: System::Boolean
true 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.

NoteNote:

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

The following code example demonstrates how to use the Multiple property to specify whether multiple items can be selected in the HtmlSelect control.
