SelectionList Class
Assembly: System.Web.Mobile (in system.web.mobile.dll)
'Declaration <ValidationPropertyAttribute("Selection")> _ Public Class SelectionList Inherits MobileControl Implements IPostBackDataHandler 'Usage Dim instance As SelectionList
/** @attribute ValidationPropertyAttribute("Selection") */
public class SelectionList extends MobileControl implements IPostBackDataHandler
ValidationPropertyAttribute("Selection") public class SelectionList extends MobileControl implements IPostBackDataHandler
The SelectionList class maintains the selection of single or multiple selected items. The SelectionList is derived directly from the MobileControl class and does not have any of the pagination handling properties, such as the ItemWeight property.
In the following code example, the DataSource property of the SelectionList class is an array of values that is created during the initial page load. You can change the setting of the SelectType property to see different versions of a SelectionList.
