PagedControl.ItemWeight Property
.NET Framework (current version)
Gets the approximate weight of a single item in the control. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.
Assembly: System.Web.Mobile (in System.Web.Mobile.dll)
A value of -1 indicates that the default weight for the element must be used. The inheriting class must override this property. For further information about overriding this property, see Pagination Support.
The following code example creates and uses a custom list control. The example demonstrates how to override the ItemWeight property of a List class to specify a new control weight.
